AGP 8x vs. PCI-E x16

[pc_boy]

is there any known performance difference between a 6600GT agp and the PCIE version other than the extra 100MHZ of mem clock?

nope. I dont know about the latest gen cards from Nvidia and ATI but the 6xxx series didn't even use any of the extra bandwidth provided by PCI-E. Even the current latest cards don't come anywhere close to taking full advantage of the 16x

ok sweet, i'm getting the evga agp one...

no card uses the full AGP bandwith yet, however PCI-E 16X is about 8 times as fast as AGP 8X
AGP 8X = 2.2GB/s
PCI-E 1X = 1GB/S
PCI-E 4X = 4GB/S
PCI-E 16X = 16GB/S
