i'm not qualified in any way to setup a rig, but i'm giving it a go with a asus supercomputer mobo, and 7 x 5770 single slot cards.. will see how it goes
You do know that there is no motherboard that can fit 7 PCI-E x16 cards, right?
Or that most decent 5770 are double slots?
Or no PSU powerful enough or probably no circuit breaker and outlet in your house powerful enough to feed that monster?
