Last year I bought the Asus cg5270 assuming that eventually I could put in a new psu and graphics card and be good to go. Now I realize that was a mistake. So here's what I want to do -
Replace the main components of the computer (motherboard, ram, psu, video card, and CPU) with these parts
Motherboard: (not 100% sure, advice would be nice)
Psu: corsair 850w
Video: gtx 570 or 580
CPU: i5 2500k
What I'm wondering is can I do just that? Will it be possible to buy those parts, keep my current case, dvd, and hd(reformat if needed) and be all set? I know it might sound strange but is this a smart idea or should I just build an entire new system?
