hi all ,i was looking at getting the msi gtx 970 seeing as it seems to be a decent mid range card and good performance for the price but it says pci-e 3.0

MSI GeForce GTX 970 GAMING TWIN FROZR V OC 4GB GDDR5
1140MHz Core, 1279MHz Boost, 7010MHz Memory, 1664 CUDA Cores, DVI-I, DVI-D, HDMI, DPort, :eek:PCIe 3.0,:eek: - Bus Type: PCI Express 3.0

does that mean my motherboard has to be pcie 3.0 for it to run properly im well confused as the motherboard i was looking to get was this one,
Intel Z97 Chipset, 4x DDR3, 3x PCI-E x16, 4x PCI-E x1, 8x SATA 6Gb/s, 1x M.2 slot, 3 Way Crossfire & 2 way SLI Support, 7.1 HD Audio, Killer GB LAN

help please can anyone clear this up
 
Nope it can run on a motherboard that has PCIe 2.0, that motherboard is PCIe 3.0 anyway. So either way nothing to worry about, good luck :)

so i dont understand the difference tbh,would it run better /faster with a motherboard with pcie 3.0?

Theoretically PCIe 3.0 has more bandwidth than PCIe 2.0, but ofc you need to use a card that can saturate that bandwidth. As far as I know, our current GPUs cannot even saturate PCIe 2.0 x16, let alone PCIe 3.0, and you may only see the benefits of PCIe 3.0 when you run 2 high-end cards in SLI. Those benefits will amount to 2-3 FPS at the most.

Note: All my information on this is a little anecdotal based on lots of reading done on various hardware fora and sites, but I believe it the advice to be pretty accurate. In short, I wouldn't worry at all about this "issue". You could probably find a number of benchmarks about this with a some google-fu.
