I'm planning a PC upgrade.

Good morning!

I'm out of the loop regarding PC hardware. My PC is quite old. I'm on meds for pain so I can't think straight. I have a 3090 and an i9 9900K with 64 GBytes of DDR4. The motherboard is the B360 AORUS GAMING 3 WI CF. My VR headset is the Reverb G2. The PSU is the Corsair HX1050. My current monitor is a 98" 4K LG SIGNAGE screen. Windows 10.

I was just looking on eBay and saw the 5090 32GB sell at auction for only £1,260 brand new. That surprised me, as I thought it would be around 3 to 4K.

What hardware would you advise with the 5090 for VR gaming? I won't play a game unless it's in VR. I've always gone with Intel for CPUs, but I'm open to buying an AMD CPU now as I've read they have surpassed Intel. I can't buy an AMD graphics card as I want the CUDA cores.

Avoid that 5090 it sounds too good to be true and you can bet it is.

I'd want to pair a 5090 with a 9800X3D (or other X3D variant). You can buy Intel (265K) if you want, but you'll be giving up some gaming performance (tweaking can gain some of this back) for better productivity/multithread.

With the high price of DDR, Intel 12th-14th is a possibility to keep what you have, but I'd only buy 13th-14th gen new with a reliably-serviced warranty due to the potential for degradation.

Damn what timeline have we fallen into when we just except £1200 as a good price for a GPU

There is no such thing as a cuda core, it’s just general purpose compute and C++ which you can run on pretty much anything.
