I am expecting @CptLucky8 to answer this but anyone can.
I have an i9-9900K, 64GB of 3600, GTX 1660 TI, M.2 NVMe SSD (970 Plus)
I want to buy an RTX 3800 (maybe TI) when prices are at MSRP at $700 USD.
I also want to buy a VR setup at $500 USD.
Can it work okay with my GTX 1660 TI?
Seems like if I’m viewing from the goggles or whatever it is called, do I
need the $700 GPU?
Maybe my real question is does the graphic resolution & FPS
of the VR display depend on the that of the GPU?
Yes, you definitely need a GPU more powerful than the 1660Ti in order to use a VR headset because of the higher number of pixels the GPU has to process compared to when you use a monitor.
I doubt the RTX 3080 will be available at MSRP this year, if I were you I’d look for a used 2080 Ti.
Sort of depends on the VR headset as well. The Reverb G2 is much more demanding than something like a Rift.
Headsets have different resolutions so this needs to be taken into account.
My old 1080ti struggled to drive my Valve Index but with the 3090 it’s as smooth as butter in IL-2, a friend flies MSFS2020 in VR with 2080 and Reverb G2 so if you are looking at a 3080ti that should definitely do the job with whatever headset you decide on.
I have a 5700XT and use the HP Reverb G2 with no issues.
I won’t say much more than what is already posted!
In short: the more, the merrier!
big and honkin
^the size of graphics card you need.
Minimum case size would need to be a full size tower as the GPU would be literally too big otherwise.
In fact, you just need a GPU that requires its own housing unit
