    is SLI preferred for oculus rift? I'm trying to figure out if I should buy one 980 or dual for elite dangerous and oculus rift

    any performance gains with oculus and sli?

    Thanks!

    LOL your'e wanting to get SLI for Oculus? From what I've heard, its absolutely necessary.. anyways, I wouldn't get SLI just for Oculus.. If you can afford it, I'd always get it..

    Multi-GPU is not preferred due to the additional latency, which is a big no-no for VR. Single GPU is best.

    Ripped from Reddit

    AnandTech | The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2

    "Lastly, NVIDIA’s fourth and final latency optimization for VR Direct is VR SLI. And this feature is simple enough: rather than using alternate frame rendering (AFR) to render both eyes at once on one GPU, split up the workload such that each GPU is working on each eye simultaneously. AFR, though highly compatible with traditional monoscopic rendering, introduces additional latency that would be undesirable for VR. By rendering each eye separately on each GPU, NVIDIA is able to apply the performance benefits of SLI to VR without creating additional latency. Given the very high performance and low latencies required for VR, it’s currently expected that most high-end games supporting VR headsets will need SLI to achieve their necessary performance, so being able to use SLI without a latency penalty will be an important part of making VR gaming commercially viable."

    On a side note, I wish I could justify the DK2.

    I want to try one out so bad.
