if you have cards with custom coolers, even those that need only 2 slots, you will for sure have heat problems, because most fan configurations need space inbetween the cards. i did choose the gigabyte geforce gtx 580, 3GB, but the pcie slot configurations of most available boards won't allow more than 2 without going for watercooling (imo)....
there was the msi big bang marshal board, but afaik it's no longer available. i think currently the evga z68 ftw is the best bet with five 16x slots (8x electrically) and one full 16x slot. and of course risers of some sort. and of course a very powerful psu and some truly advanced cooling solutionp3taoctane wrote:Gidday t_3
What kind of MOB's are running 8 580s I have been trying to find one. With no luck. Are they custom built or something?
I am guessing 580s will be a lot cheaper in a few months
Thanks
still it could be the case that one 680 will match two 580s price- and performance wise, and a quad card config would save a lot headache with cooling and building such a rig...
wee need to wait for an octane update for the new architecture, *) because octane doesn't work with the kepler for now. so the question is more how long this will last. at least from synthetic benchmarks it looks like a 680 is a little faster than a 590, but because of the different architecture in kepler, you can't just count cuda cores. also this will have to be proven in real word *)ssokol wrote:hemm
1536 CUDA cores , and 2GB in GTX 680.....
co I think I will buy it, better than 2x GTX 580 (512 CUDA cores) , even that GTX 580 has 3GB.
What you think?
