I have just bought 3 1080p IPS monitors.
Will be using for multi tasking, and predominantly gaming. Mainly a FPS gamer and in particular, BF3.

I was thinking that with a resolution of 5760x1080, and a 770 with only 2GB of VRAM and even if put in SLI (im a noob at SLI info) I believe it wont stack, say 4GB of VRAM.
So would a single 780 with 3GB of VRAM be sufficient?

Budget is from a single 770 (£360) to SLI 770 (£720)

Thanks all in advanced.

Are the 4GB versions even out yet?

Oh and also, forgot to mention, im going to be watercooling and two cards on water will just be too expensive with the two waterblocks and all.
So with that information, Watercooled single 780 or AirCooled dual/single 770?
 


+1 to that. If you want to game at ultra, a GTX780 will handle most games at 5760x1080, but you'd have to drop settings a bit on Crysis 3, Far Cry 3, Hitman 5, Metro Last Light etc - the more demanding games. I'd go with GTX770s.

I wouldn't concern yourself too much with the actualy amount of VRAM. Anything over 2GB should be fine. Instead compare the actual memory bandwidth. 255GB/s on the GTX 780 vs 224GB/s on the GTX 770.

I run two 4GB GTX 680s in surround at 5760 x 1080. The highest I've ever seen my frame buffer go was about 3GB. In BF3 my average is 1GB per card. I can play BF3 on Ultra with some of the AA settings turned down. It ranges about 30-40 FPS, and sometimes dips into the 20s.

Either go with an SLi GTX 770 2GB setup, or get one GTX 780 and get a second one when you can. 5760 x 1080 is a beast, you'll need all the horsepower you can get. I'm still not 100% satisfied with the performance from two GTX 680s, and I'm actually in the EVGA Step-Up queue for a pair of GTX 780s.
