Could someone recommend the best motherboards that have 4 PCI Express v2.0 x16 slots, which will allow to plug 4 cards with 3870 HD GPUs to be used for stream computing? (Each of these cards takes space for 2 slots.) It would be great if there is a separete PCI slot that will not be overlapped by the 4 cards.
The motherboards should take ECC emory that is as fast as possible, but at least 800 MHz.
How about motherboards like the above that have 1 CPU socket?
How about 2 CPU sockets?
And how about 4 CPU sockets?
