I just sold my beloved EVGA 8800 GT OC to a friend that needed it. I picked up a 5850 just now and realized that i no longer have physx support. Do i really need it for games these days? The only game that i might still play that needs it would be NFS Shift. And if i do need it, a GT 220 should be enough just to process physx right? I could just use my 5850 for graphics and a cheap GT220 for physx. But then if i do that, would my motherboard (P5Q Deluxe) split into 8x/8x? Will it bottleneck my 5850?
