So Im looking for a gaming pc for around 550-650 and I found 3 builds I'm quite fond of that are quite similair and cannot decide which is better. This is my first build and am not very knowledgeable in this area. These are the three builds http:// http:// http:// for the youtube video look at the description. I might consider adding a 32-128 gb SSD on any of the builds so please state if that will be a problem. Finally, is Windows 8 or 7 a better option if I play games such as WoW, Diablo 3, Minecraft, Battlefield 4, and Bioshock Infinite (Maybe recording some) Thank you for your help.
