The 7990 was a dual-GPU card with, IIRC, two of the 7970's chip on a single PCB. So if you actually have two of them, you essentially have four 7970's in this system. Your specs look like someone had way more money than sense about a decade ago. 

 

Unfortunately, since Crossfire is deader than disco, in terms of actual performance in modern games you functionally just have one (downclocked) 7970 in you system, and the other three chips are doing fuck all. And even the normal 7970 performs basically like a 1050 ti (to find a "current" GPU to compare it to) which would certainly not be my weapon of choice for VR. All that RAM is going to be about as useful as tits on a bull, and you didn't specify what "i7 extreme" you have but if it's of a similar vintage as your GPU's then a modern i3 will run rings around it. 

 

My recommendation would be get what you can out of selling the parts of this relic e-peen build (7990's have sold recently for about $150 on eBay to people who just collect old GPU's) and start building a sensible mid-range modern system. 

 

 

Your "PC master race" thing is cringe.

i dont think your correct becuase ive asked other people and they said it will work fine as the oculus quest 2 has a built in gpu with intergrated graphics and also the equivilent to the amd hd 7990 is the gtx 680 wich works fine with vr

I don't think you understand the difference between using the Quest 2 to play games from the Quest Store and using the Quest 2 as a headset to play games in Steam VR.

 

Here is the list of supported GPU's for using the Quest 2 connected to a PC: https://store.facebook.com/help/quest/articles/headsets-and-accessories/oculus-link/oculus-link-compatibility/ You will note on the AMD side there's only compatibility back as far as the RX 400 series. 

 

Even if your cards were technically compatible, they are way less powerful than even the least powerful cards on that list.

It will probably not work at all, and if it does "work" the performance will be atrocious.

There isn't any such thing as the "9000 series AMD" so forgive me if I'm skeptical.

 

I already showed you what Meta says. Here's what Valve says:

Well then why are you wasting my time and yours posting here when you have the wisdom of your dad (who is clearly an expert at spending money if nothing else) and the "loads of other people" to rely on?

 

God, this build though. I can just picture your pops walking into the computer store and telling them he wanted a "future-proof" computer that would "last him ten years" and all the salesmen giving each other high-fives when they sent him home with the parts for this monstrosity. 

 

Have fun with your Quest 2, or not, I won't know either way because I'm putting you on my ignore list now.

Of course your dad said it will work well, he don't want to spend money on a new GPU. 

 

You can use 7990 for VR but performance will be atrocious.

It's another classic case of seeking confirmation, not advice. Though I'm jealous. I'd love an x79 system.

You got a single HD7990, it shows up as 2 graphics cards as HD7990 is a dual GPU card. As far as steam VR goes, that is a GCN1.0 card and is 10 years old at this point. Crossfire may not be supported by steam vr games so I doubt you will have a great experience with that graphics card.

 

I am also extremely doubtful that you got an i9.

Crossfire (and SLI) are not supported by most steam VR games. Additionally, your gpus, while high end 10 years ago, aren’t sufficient to run most modern titles in terms of raw power.

 

Best bet would be to invest in a new card.

Simply put you have 1 hd 7970 in your system for as far as vr games care. Those other 3 cards are dead weight.

 

A hd 7970 will do games like beatsaber pretty well but anything more advanced is a flat out no as performance will be low enough to cause motion sickness.

 

Id also just sell that second hd7990 whilst they still have a tiny bit of value. Even when sli and crossfire was used adding a 3rd or more card except for benchmarks did nothing.

Nope

 

1) Crossfire is pretty much dead

 

2) SteamVR cant run on those GCN 1 GPUs

 

if you want a gpu vr i'd recommend waiting for RTX 4000/RX 7000 and getting a 2080 if you can
