Hi, all! I just finished my first build, based on MSI Z97 Gaming 5 LGA 1150, with a i7-4790K and GeForce GTX 970 4Gb. Probably not the most prudent set up for the first build, but I wanted a good set up. My question is: I'd like to stay with Win 7 Pro, not a big fan of Win 8, and a little suspicious about Win 10. Would anyone know of any issue that would come up from going with Win 7? Thanks in advance!
