Graphics card comparison

[ostenfeld]

I am considering to buy a top-of-the-line computer for MSFS. I see a fairly substantial price difference between PC's with nVidia 4080 and 4090 graphics cards. Would the performance be much different between the two cards - your experience and/or opinion or experience please.

Unless you're trying to run a high res VR setup or multiple 4k monitors, it won't make a difference, as the limiting factor will be the CPU and not the GPU.

Thanks - that makes good sense!

Will a i9 14900k help ?

My 12900k gets only 20% Usage in VR with 45fps on REPRO fixed at 45. It's all about keeping it with the GPU VRAM size limit which mine is 10GB but adequate to be smooth. VRAM uses DDR5 which most m/b are not using and so the bleed over is the bottleneck here. Top end obviously you want a 4090 with 24GB VRAM and a big enough case with enough PSU Watts for this and headroom on top with good cooling.

I believe mine bricked the m/b with the last BIOS I Updated to and some are known to Delete the FAN SPEEDS on 3080 cards. Mine hardly powered up the fans at all which should spin at 55C and ramp up like they do for my older PC with 2080TI.

You should approach a specialised Top Spec PC Builder as there are many traps including some m/b only run at 4400 even though you buy 4800. 2 Pairs are the best combo for speed. Then again if you use 4 sticks then the speed goes down further so I suggest 2x 32GB DDR5 RAM.

Be sure you get an ATX style PSU as DELL use their own crap flat design with fans which can not be controlled inside and are noisy and are flat on the base. Utter crap design and utter crap at stocking all Parts for anything. They also do NOT Export all their USA Parts to Rest Of The World because they are Cheap Charlies but Trade here to UK is in place. They lie on every aspect of HELP.

*Be sue you run it all via a UPS direct from the Wall Socket and not use Multi-Socket Boards. e.g. https://brd.tripplite.com/en-us/pure-sine-wave-gaming-ups

I've just been using a power strip with my gaming PC for years without any issues.
Is the UPS thing really worth it?

Only if you live somewhere where you have a reasonable risk of repeated outages. Otherwise it's a waste of money and electricity.
A good powerstrip with surge protection will handle your PC setup just fine, unless you also plan to put other extremely demanding appliances into the same strip. So maybe plug your immersion heater, electric tea kettle and AC into another socket.

Yes. No. Maybe?
If you're already in your GPU limit it won't do scrap to upgrade your CPU. If you're CPU-throttled, it will. That depends on your hardware and settings.

For me I got one due to losing my onboard Ethernet from a Power Spike which had my house lights merely flicker off/on. I have not yet tried a complete OS install to find out if the motherboard has damage but it is common in these cases to get corrupted registry. They are costly and only last around 3yrs before needing new Batteries and so base it on that and if worth saving you either losing data or needing a new OS install in such a case without one but get the VA size correct for today's power usage...

Thanks for all the good points made. Some manufacturers are not inclined to tell you the power rating of the PS - an important consideration IMO.

If you have the money, 4090 is the card to buy and I don't mean just by performance.

4090 gives better value i.e performance/$ than 4080. Its the first time that a high end GPU gave better value than a mid range. (Ofcourse I am talking about MRRP price of $1600}
