yes but but the gpu's will face heat problems as there will be no breathing space between them.only good solution is to go with liquid cooling system on your gpus.
BTW,i don't see a good reason behind 4x 680s? what are you planning to do?
To start with. Ill just use 1 gfx card but asap nvidia gets kepler under control which they will... eventually..
Then Ill be prepaired for an upgrade.
But untill then I would like to keep my computer in the office. with air cooling
But when I add 3 more cards I guess Ill just have to move it to the server room.
And then add watercooling I guess;)
I just still can't decide on the freaking case.. worst piece of hardware to decide I think;)
Worksstation cards sux for the price.. had 2 quadros sofar and cheaper gamer cards beat em. I believe in maybe 6 months there will not be a single prof card left on the office.
Quadro 6000 or 7000 might be up for the task but they cost more than the total of my rig. Quadro 7000 actually cost 5 times the price of my rig. For underclocked.. overcooled cards.
And havent had the need for 6 or 12gb vram yet either. A few times 2 gb wasnt enough and I had to do stuff.. so Im figureing 4 gb is pretty futureproof.
