Hey guys I am building my first PC and am undecided in the motherboard. Originally I wanted a 3570k and a $140 asrock z77 but I was a bit over budget. Instead I will opt for a 2500k and hopefully a board around 100$ if I can. Is it true that I need a z77 for IB processor? I looking to get a gtx 570 if I can fit it into my budget. Also do only certain boards support 1600mhz RAM? I will never SLI if that matters which options I can eliminate, I will obviously also do some light OCing. If you guys could suggest some boards that fulfill all of my requirements for around $100 that would be great( I need a z68, right?). Thanks in advance.
