My friend wants me to take his build for $400 and a 1980 x 1280 monitr 21.5" for $50 so he can upgrade and we can play together. It has a gtx 570 with a corsair 750 watt 80 plus bronze with a quad core cpu at 3.2ghz i forgot what it was. Is it a good deal considering my budget? Also, what is the best usb wifi adapter thng for gaming at max $35. I have a centurylink modem if tht helps.
