Whatever you do, NF200 is useless.
We are talking about "virtual 4x16 PCI-E"
All depend on X58:
1 vga = 1 x16 PCI-E
2 vgas = 2 x16 PCI-E
3 vgas = 2 x16 + 1 x4 PCI-E or 1 x16 + 2 x8
4 vgas = 4 x8 PCI-E
So how can NF200 handle 4 x16 PCI-E?
It's useless, it adds only latency.
All above are hipro5's words from a greek forum.....
