Guys, Planning to buy a second Nvidia card for my system. I want to know the best card out there for folding. I dont care about power requirements. Highest ppd and least time for WU to complete are my primary concerns. Please let me know your suggestions. Also whats the effect of GDDR2 and GDDR3 memory, bus width and PCI-e Version (V1 vs V2) on folding performance? The reason I ask is that I added a second GPU that was around: MSI Nvidia 8400GS w 256MB of DDR2 @459MHz Core and 918MHz Shader. Fahmon indicated a PPD of only 500 (Physx disabled)!! My current master folder is my XFX 9800GTX Black Edition w 512MB of GDDR3 @760MHz Core and 1900MHz Shader Watercooled with a avg. PPD of 6000-6200 @55-59 Degree C Temps Appreciate your help!!
