7800X3D matches the i9-14900K in gaming performance, the Thermalright PA120SE is more than enough to handle it, and your budget is more than enough to fit a 4080 SUPER or RX 7900-XTX when you don't overspend on premium priced coolers and overkill motherboards and power supplies
If you need more cores then you could step it up to a 7900X or 7950X but if you're just gaming then the Ryzen 7 is more than fine

The calculation you should be using to buy your first G.P.U. is C.P.U. watts + G.P.U. watts + 300 watts[www.corsair.com] according to corsair. That extra 300 watts accounts for all auxiliary components and peripherals, with 150 watts of headroom for future proofing against subsequent upgrades.
245(12900)+ 285 (4070 Ti)+300=830. You should be looking at 850 watt power supplies. Maybe thousand watt power supplies if you're particularly concerned about future proofing. There also isn't very much of a difference between the efficiency between platinum and titanium power supplies. I think most people would buy bronze or gold these days. If you used a less power hungry C.P.U., you could get away with an even weaker power supply, but 850 lets you get away with most configurations presently on the market.
Keeping in mind that efficiency may be a legitimate concern, the power supply I would advise you to buy right now is the Be Quiet BN515 Straight Power[www.amazon.com].
It's only $160 on Amazon with a 24% discount right now. That cuts $200 off of your original build right there without changing anything that would affect the performance of your build.
Also, I might say you could go with an air cooler for much cheaper than a liquid cooler. Noctua just unveiled their second gen NH-D15 cooler recently[www.tomshardware.com]. I'm not sure if it is out yet, but the existing gen 1. version only has an M.S.R.P. of $120. If the cost is about the same, it undercuts the $275 price tag of the kraken liquid cooler down by $155. Some people might argue you can get away with an even cheaper air cooler, but I'm playing it on the safe side by going with the king of the heap among air coolers. I've heard advances in air cooling have been catching up with A.I.O. liquid cooling anyway.
The 12900kf[pcpartpicker.com] is cheaper than the 12900k. The only sacrifice you're making in that regard is the integrated G.P.U., which you're probably not going to be using with a 4070 ti.
It's only saving you like, $15, but it's still $15 you have no real reason to spend. If you need a spare G.P.U. to trouble shoot, it'd be better to spend that cash on some old obsolete G.P.U. off of ebay that you can keep separate from the system across builds than to pay $15 for a new integrated G.P.U.
The only thing that really justifies intel igpu when you have a discrete G.P.U. is to take advantage of the unified memory feature with Intel's own arc cards, but Intel doesn't make a card on the level of the 4070 ti anyway. I've seen it suggested that intel's video decoder on the integrated G.P.U. might be better than what A.M.D. uses on their discrete cards, but how likely are you to even care about that, and even if you did, Nvidia's kind of the top dog in this department anyway.
This might technically break the rules, but I might suggest buying a cheaper S.S.D. too. A 2 terabyte crucial P3 Plus[pcpartpicker.com] is still a pretty good drive from a well reputed brand and it only costs 118 instead of $160, saving you another $42. Tallying up the savings: 200+135+15+40 represents a savings of $290 without changing your core components.
However, it's also worth bearing in mind that the differences between variants of the same G.P.U. are marginal at best. A stock overclock might represent a 2% higher clock-speed on the G.P.U. than normal. It's almost always going to represent a better price to performance ratio to go with the cheapest variant of a card. This M.S.I. 4070 Ti slim is only $710[us-store.msi.com] on sale, direct from M.S.I., which saves you another $76, bringing your total savings up to $366 without a significant performance loss.
Finally, it's worth mentioning that A.M.D. announced new processors at computex earlier this month. If you can wait until sometime in July, you're possibly to have more processor options and lower prices on the existing processors and motherboards. Arrow Lake processors on the LGA 1851 socket are expected soon too. As such, I'd personally be weary of investing into a high end LGA 1700 motherboard/processor since it's a known dead platform, and you're not going to have much of an upgrade path on it.
Also, regarding the 3D Vcache chips like the 7800x3D, gaming performance might be improved, but only in games that utilize the extra cache, and when the extra cache isn't utilized, they perform worse.
Why? They're heat sensitive, so they're underclocked and locked compared to the normal variants.
Only get a 3D vcache chip if gaming is all you care about. Otherwise, even though the 7800x3D might remain king of the heap for general gaming, A.M.D. suggests the 9000 series chips shouldn't be too far behind.[www.tomshardware.com]
Nothing that they release in first wave will beat the 7800X3D. Really not worth considering until they get their 9000 series X3D CPUs out later.
You caught me just as I was adding an edit to my post. 9000 series might not be too far behind, so it really depends upon pricing, and whether or not general processing power is at all important. Like, a youtube let's player might benefit more from a non-3D chip because they do video editing and streaming.
Also, given that the 12900k was the chip in the original build, that's our target to beat for the purposes of our thread. 9000 series might very well do that in a lower pricing tier.
thanks guys.
moderator may close this thread now.
I got the best of the best in my build and had the 4090 on an open bench. the new 16pin cable was not bent and it was properly seated.
the hilarious part about is that, first time I used it with a 75% powerlimit to avoid this issue. second time I used a 45% powerlimit and it still happened despite open bench.
which makes me believe that 4070ti and 4080 got the same issue but less people are reporting it online.
I don't entirely doubt you, but I've just gone over that in another thread before posting here.
To make a long story short, the rated power draw given by companies like Nvidia, Asus and M.S.I. for a typical R.T.X. 4090 is 450 watts, which is supposed to be representative of its maximum expected sustained power draw draw.
It's possible for an RTX 4090 to have excursions that exceed that amount, but it scarcely matters because a power supply should be able to handle excursions above its power rating momentarily. The typical rule of thumb is that a good power supply from a semi-reputable company should be able to handle momentary excursions up to 30% greater than its labled rating.
That is to say, the typical 850 watt power supply should be able to handle up to 1105 watts for 10 milliseconds before it trips, and a 1000 watt power supply should be able to handle 1300 watts for 10 milliseconds before it trips. So a thousand watts from the two core components is rather quite unlikely to be a problem.
An ATX 3.0 power supply like the one I provided can incur an even greater power draw than that. It's supposed to be able to handle transient spikes in excess of 100% of the rated load: Ergo, an 850 A.T.X. 3.0 watt power supply should be able to handle 1500 watts, for a moment.
To the extent I do doubt you, I've been shown reviews for the Founder's Edition[www.techpowerup.com] and the Strix[www.techpowerup.com], which show that the spike power draw for the two cards is 500 and 550 respectively, which isn't quite 600 in any case. Plus actual maximum sustained draw is 468 and 477 for each respective card, which really isn't all that far beyond spec., and still falls reasonably close to that 850 watt recommendation.
Also, if we look at prebuilt computers configured with a 14900k and an RTX 4090 from reputable companies, such as the $4000 M.S.R.P. Corsair i7500[http//VENGEANCE+i7500] or the ibuypower RDY Element Hybrid Max III[www.ibuypower.com], or the Origin P.C. 7000x R.T.S.[www.originpc.com], those all come with thousand watt power supplies. These companies have reputation at stake and money to lose from R.M.As. if they underspec. the power supply beyond a few reasonable outlier cases. The ibuypower box even has an overclocked hybrid watercooled G.P.U.
It stands to reason that a power supply in exceess thousand watts is overspecced. Also, while Nvidia's spec. for the rtx 4090 is a 450 watt T.D.P., other cards consume considerably less. A.M.D's. spec. for the 7900xtx is 95 watts less, and the 4080 super draws 120 watts less.
There's no way even the highliest of 4070 ti based systems is going to need 1600 watts per the original build if even the lowliest of 14900/4090 based systems can make do with 1000 watts, because the 4070 ti draws significantly less power, which is my point.
Most computers are replaced annually, especially if someone is spending $2000 - $4000 USD on a computer when built. Most people keep a computer right at about 5 years. Capacitors in all power supplies degrade a little over time depending on utilization. If a power supply is run at 90% of it's rated load (with frequent spikes over it's rated capacity) it's entire life then it may degrade as much as -2% to -5% each year. Power supplies fail faster if they are loaded more. This is another reason why typically we want to over-budget a power supply above what the computer will use, not where it's typical load will almost max out the power supply daily.
The Power Supply is over kill as well.
You can probably get cheaper RAM if you leave off the lights too.
