Solution
If at $1260 and can go $1,400, the 7870s go around $175 or so, (not sure what model you are looking at) but could prob move up to a 280X, many are right at $300, I just picked up the Asus 280X yesterday, great GPU! ;)

My Budget From what my mother said is about $1200-1400
Any upgrades that fall into that category?
