Hey guys

i have noticed alot of cards coming out that are PCI express 3.0. Is 2.0 to slow for powerful cards now?

Correct me if I am wrong. PCI Express 3.0 would increase the bandwidth & transfer rate, but mainboards as of today With PCI Express 2.0 slots should have enough bandwidth so you wont be Limited by Your mainboard With 3.0 GPU's, unless maybe if you will be doing quad setups, though I am not sure how that exactly Works.

PCIe 2.0 is more than fast enough for any modern video card.

Pcie x 16 3.0 cards are backwards compatible. The only issue is that they will not be able to perform at their fullest in a Pcie x16 2.0 slot. PCI 4.0 will be coming out in 2014/2015, so now or next year is the perfect time to upgrade that Mobo of yours to a mobo with a chipset that supports pcie x 16 3.0.

@banishedsoul1: Current cards (meaning currently on market Nvidia GTX 6 cards and ATI top of the line ards) do not see any performance decrease on PCIe 2.0 vs 3.0, at least not within the margin of error. That could change on the next generation of cards, especially with the revelations today about nanotubes being functional, but we'll see.
