hi, i was going to upgrade my gf's pc and mine. she would get my cpu, gpu and psu. and i would get new faster bits etc. this would cost me around £500. but i have now decided to give her my pc (asus 970 mobo, phenom x2 550 @3.7 on air and a 5770) i need it for games, research has told me to buy a 2500k system, i have no problem with this however i do not understand how the intel mobo system works, what socket to get or what chipset. i will be pairing up with a £200 gpu when i have decided what gpu to get. (waiting on 7xxx pricing). i will be building fulll system and need some serious help. i dont want to spend more than £700 on hardware. but if it gets me a better system than my old amd system(which worked pretty well to be honest)then i think it will be worth it
