I bought a couple of Inpiron laptops for my nephews Xmas present on the Dell Outlet for just over £300, so probably cheaper to you in the Land of the Free.
Both are i5 3xxx (2.5 to 3.2 I think). One has a 7670 and the other a 7730, both run really well on the settings I normally use(no shadows or AA and high everything else). but the 7730 is 10fps better on tython (so 50 and 60fps)
I added a 128gb £50 Sandisk 500/350mb/s SSD and have been greatly impressed with them (obviously I removed the Dell Bloatware by doing a clean install), basically my nephews have better systems than me now.
