So I'm finally in possesion of all the lovely little hardware for my computer and am going to start installing all the goodies tomorrow. new PSU (antec true power new 650w) new MB ( sabertooth x79) new cpu fan ( noctua nh-c14) and most importantly a new gpu (PNY gtx 570, for just over £200) Any advice on the order of installation? I was thinking PSU, boot and test, MB + CPU + CPU fan, boot and test, finally gtx 570 or should i just install everything and pray for the best?
