Hey guys i am going to get a new msi gtx 970 gaming 4g. But i haven't upgraded my motherboard in a while. It's the same old Gigabyte h55m-s2v. My question is if they both are compatible with each other. I'm building a new rig soon but until then i have to play with that mobo. So help guys, are they compatible with each other? Would i require a BIOS update to run the 970?
