I have a 295x2 right now, but I need CUDA cores for rendering, is it worth to trade my card for 2 690s?

Which of these cards would be better in games? The single 295x2 or dual 690s?

I am also gaming at 5760x1080 so will VRAM be a problem?

Dual 690s would be 4 GPUs, so I am going to have to assume that will probably take the edge in raw performance.

VRAM is a serious concern though at that resolution. Each 690 GPU only has 2GB so the R9-295X2 will do better in gaming at high resolutions I would think.

(Not a very common comparison, so I am going with general benchmark knowledge between R9-290X and GTX680s.)

A 295x2 is the best GPU for gaming right now (single). It is a better setup than two 690s. It has 2x the VRAM (4GB per GPU vs 2GB per GPU) and is way better for the resolution you are gaming at.

Just a way to show you, a single 295x2 is about double the performance of a single GTX 690 and SLI/CFX does not scale 100%, especially beyond 2 GPUs, so you wont get double the performance.

For gaming the 295x2 is a better choice.

Did you see the benchmarks from the first few 980ti's reviews?

http://www.tomshardware.com/reviews/nvidia-geforce-gtx-980-ti,4164-4.html

Maybe a pair, or more, of 980ti's........

Or probably best of all, wait a couple months for 3xx Radeon cards with HBM memory to see how those benchmarks look.

I mean, it's not like the card you have now is exactly a slouch.....

Also, would the 6xx Nvidia cards be able to support DX12 etc? Even with the ridiculous amount of cuda cores it would give you, I would think a newer/latest gen card of whatever colour would be superior.
