Upgrade CPU for RTX 3070

So I got a 3070 for cheap (200€) and now I need to upgrade my CPU so it doesn't get bottlenecked.

I am currently considering 5800 or 5800X3D.

Also what mainboard to get?

Is the X3D worth it over the normal 5800X?

Thanks

X3D is a lot better, I made the move from the normal 5800X myself.

But a 3070 is too slow to be bottlenecked.

so a 7700k wont bottleneck it? at 1080p

A 5800X won't, there was no mention of a 7700K.

You said a 3070 is too slow to be bottlenecked... It depends on the CPU of course

You never mentioned which CPU, you said 5800X and 5800X3D, so therefor the 5800X is not going to bottleneck such a slow card.

It's hardly a slow card any more than the 5800X/3d is, a slow cpu.

As to the OP, yeah upgrading to a 5800X/3d or a 12700k or 13600k would all be fairly affordable and substantial upgrades.

7700k is the best cpu for that board
upgrade will need new mobo, also new ram if you go to ddr5

Yes, I know.

I thought about going with an AM4 plattform so I can keep my DDR4 RAM.

Is the 5800X basically the go to? Or should I get the more expensive 5800X3D?

Or is there a better Intel CPU + board combo for the same price?

I dont see how a 3070 would bottleneck a 5600X, even on 1080p......

5600X + Aorus Elite v2 for aprox 250 bucks (depends where you live) and you are good to go. Maybe some 3200mhz Ballistix for 100 bucks and even a 3080 wont be bottlenecked by that setup.

Sell your old mobo + CPU and ram sticks [your RAM is fine] and you should get a pretty decent deal. The Pro Carbon is selling for around 90-120 bucks on ebay. USED!!!

edit:
To answer your question, yes, the 5800X3D is worth it big time compared to the 5800X and will gain you some huge improvements on lows and highs, but only if you got the goods. (6900XT/3080TI and higher)

If you're looking at AM4 and not looking at the 5800X3D, then the alternative should generally be the 5700X instead of the 5800X. It's currently about $20 cheaper and yeah that's not a whole lot (this represents about 10% of the price), but they're also practically identical in performance.

In other words, make your comparison between the 5700X or 5800X3D. Either are viable really, depending on how much you want to go.

What DDR4 RAM for you have? With a 7700K I'm almost expecting 3,200 MHz at most, possibly slower? Ryzen (on AM4 since 3000 series) really wants 3,600 MHz RAM, as you slow the Infinity Fabric down with slower RAM, but 3,200 MHz is more than okay. The X3D CPU in particular is less finicky about slower RAM (more CPU cache means more cache "hits" meaning less fetching to RAM meaning it matters a bit less), so if you have something like, say, upper 2,000 MHz range like 2,866 MHz/2,933 MHz I'd say that might skew things towards a 5800X3D over a 5700X if you want to reuse existing RAM. If it's more like 2,600 MHz or lower I'd say you're looking at considerably losing speed and it would warrant replacing it instead, which then brings up if that ties you to AM4 or not (keep in mind LGA 1700 can use DDR4 too, but I similarly wouldn't reuse slow DDR4 with it)

Intel's 12th generation chips can also be found at very good pricing.

If you have a Micro Center nearby, for example, the 12900K, a Z690 board, and 32 GB DDR5 RAM is routinely $399 (just got another e-mail advertising it this morning). That's hard to beat honestly.

Julien, cut it out. 2023 年 9 月 29 日下午 2:38

Your current system might be bottlenecking the GPU. The answer depends on the context, i.e. game, graphics settings, FPS target/ refresh rate.

I suggest to try Intle Presentmon[game.intel.com]. The values of Frametime and GPUBusy provide an answer if a CPU bottleneck occurs and by how much a more powerful CPU can increase the performance.

3200 cl14 ram is pretty good
it will be ok for the 5800x/x3d cpus

or you can keep it with the i7 for a htpc or other build

microcenter always has the best cpu/mobo combos, and sometimes good ram deals
they can price match amazon newegg and a few other stores
but gotta go there in person
