err as cheap as possible lol but will probably buy it piece at a time
i have my current pc which i can scavenge things from like the HDD and dvd drive and graphics card to begin with.
i am also running two monitors and would like to keep this and maybe upgrade to three monitors if possible
i will need to buy a copy of windows 7
For the cpu and mobo I'd go with the new i3 3220 and asrock z77 pro3. That way you could upgrade to a i5 3570k later if you wanted but you'll probably be ok with the i3 for a while cpu aren't that important in gaming the gpu is way more important. You don't need 16gb of ram for gaming 8gb is more than enough and get the low profile corsair vengeance or g.skill ares 8gb. Now for the gpu I'd spend an extra $40 and get a hd 7850 or a little more and get the 7870. You said you could scavenge from your current pc a graphics card so does that mean you have a hd 6870 already? If you do just get a second one and 750w psu.
