Ok, so I’ve heard a lot of crap going around about PCI-e x16 being maxed out. Well since I own a pretty decent card (GTX 260) and a motherboard that happens to have x16, x8, x4, and an x1 slot, I figured I would test some stuff out.
FPS average (3x through the GPU bench in Crysis):
x16: 30fps
x8: 30fps
x4: 27fps
I think this proves we really don’t need x16 yet (maybe for dual GPU cards, but even then I’m not sure, as x4 is almost enough).
