Card specs and the differnce

[andy_93]

Hi all, I am looking at venturing into VR in the next few months but my PC does not quite reach recommended specs published by Steam. For those who have ran the Steam VR app will know what I mean when I say that I was in the higher end of the middle bar, the yellow or amber coloured one. So that I could run it but not how its meant to be run. So my question is about stream processors. I am running two 7950 oc editions in CF. Each have 1792 Processing units. now I know that the memory does not double up, so each card has 3GB of ram, that does not make 6GB of ram but is that the same as stream processing units. The reason I ask is that some of the GPU`s that are recommended by Oculus only have 2304 SP (RX 480). So, with that said my two cards should easily run Oculus, even one tbh as apart from memory there is not much difference, to me anyway but I am not that clever, so that's not saying much. So could someone explain to me why this is as I don't know what card to get. I am not buying Nvidia, to expensive so as the 480 is the newest card, I thought that would be the best to go for but looking at specs, the 390x and the Fury beat hands down, I am so confused, please help.
Many thanks.

This will sound like a pretty shit answer but there is more to a card than just the numbers.

I'm not sure the whole science behind VR and what it wants so I just go off if min specs. I have a PC with a 970 and 4690K which is almost completely min specs. Using a DK2, it handles all games pretty well.

Hi, thank you for your reply, its not a shite answer, any info that people contribute is of help, so many thanks for your input. Looking at the CV1 edition of Oculus, the 970 will run it as it is on the list of recommended cards but for the fuller experience, they recommend the 980 but Nvidia cards are son expensive.

To my knowledge the Oculus does not support SLI so if you buy the CV1 you will be running it off of 1 gpu. Maybe that has changed, but not as far I'm aware. For me personally, the resolution on current VR is such that you get a pretty intense screen door effect if you focus. Because of that, I'd like to max out the graphics as much as I can seeing as some of the text is hard to read even on the home screen. To be honest i'd recommend going with at least the 970.

Hi lun4ice, thank you for your reply, I have heard about the screen door effect and seen a little bit of it on YouTube. I mostly play Assetto Corsa which runs horribly in CrossFire so i have to turn it off, so that's one of the reasons i wanted info on a single card but it has to be AMD as i cannot justify the money Nvidia charge for there cards. They might be the best performing cards but at a premium. I feel AMD offer best bang for buck and a better priced upgrade with the Oculus costing £550 so another £500-£600 for a Nvidia GPU is out of the question.
