Hello all,
I am building my first computer. I am finding out that the graphics card i want(ASUS GTX 660 Ti) is pci-e 3.0 where the motherboard i think i want(ASUS M5A97 LE R2.0) is pci-e 2.0.
My question is if this will matter? Will the motherboard slow down the graphics card?

Full build info (Budget build):
mobo: ASUS M5A97 LE R2.0
CPU: AMD phenom II x4 965 Black edition
RAM: G.Skill sniper series 8 GB
Video: ASUS GTX660 Ti
Power: CoolerMaster Silent Pro M700
HD: SeaGate Barracuda ST2000DM001

Any advice will be appreciated. Thank you
