So I'm building a PC for the first time and I'd like some thoughts on if it's good or bad. Are all the parts compatible? Could I use any other parts that are cheaper but don't sacrifice performance. In the future I plan to get another gtx 770 in SLI, will there be enough wattage? I don't plan on overclocking. I'll be using this PC for mainly gaming. Budget is under $1500.
