Dual SLI Help

[Ranger1979]

:confused: Hey guys I want to pick your collective brains, I just purchased another EVGA 6800 GT 256MB PCI-E Video card. What Can I do to get the best performance out of the cards running in Dual SLI mode? Any Suggestions on how to boost my System performance overall is welcome

Thanks

Here's what I am running

AMD Athlon64 3200 Winchester

ASUS A8N-SLI Mother Board

2 GB DDR

Raid 1 Striping WD 74GB SATA Drives

EVGA 6800 GT 256MB PCI- E

Use latest drivers and make sure both cards have enough power(strong PSU). 500watts would be good. :)
