Whats the max GPU's i can have per computer?
Whats the best OS to install on the computers?
Do i need to spend a mouse,keyboard,lcd for each computer? Cant i make some sort of cloud for one computer?
Consider these ATI cards:
7950: 175€ - 200€, 650 Kh/s
6950(used): ~110€, 450 Kh/s
5850(used): ~60€, 400 Kh/s
7990: 520€ , 1200 Kh/s (bad €/Kh ratio, but higher density)
