I recently built a new gaming pc. .. my specifications are :
AMD a8 6600k black edition 3.9 GHz overclock 4.1-4.2 GHz
Gigabyte GA-G1 sniper a88x motherboard bios version F8
Corsair Vengeance 8 GB ( 2x4 GB) 1600 mhz dual channel memory
Cooler master K281 mid tower cabinet
I am thinking to get a new AMD ATI Radeon R9 series graphics card. But all these graphics cards are PCIe 3.0. My motherboard have PCIe 3.0 slot but motherboard's manual says that you must install a FM2+ cpu. My cpu is FM2. Can my pc will support the graphics card. If not, give me some suggestions. .....
