what would be the best card gaming at 3840x2160 30fps?
its only a quick fix until HDMI 2.0 is available on a GPU, so im not going to spend big bucks just yet. I just want something that can game at 4K 30fps. My budget is $500AUD
Im running 2 X GTX570's at the moment so im a bit out of date for now
My system is the following

Intel 17-3960X 3.30Ghz
32GB ram
Asus P9X79 Deluxe
2 X GTX570
Corsair 850Wat PSU
 
Solution
Sli 760 is better than 280x. A single 760 4gb is easily defeated by 280x since 760 memory bus is small, and will limit output of 760. 2x 280x would be better than sli 760 4gb in any resolution.

I think i might go with the 280x 3G but the GTX760 4G is also in mind
The only thing thing that makes me a bit undecided is that the GTX760 has 1G more then the 280x.
I know at 3840x2160 im going to need all the Vram i can get, so when you say that the Vram dont stack up, dose that mean if i pair these cards, the GTX760 together will still only have 1 G more then the 280x? As to being 2G more?
