Hello,looking for $200-$250 single video card to run with I7-730 OC at 3.9G - HD5830 best bet? I will have a corsair CMPSU-750TX. I use a 24 wide 1900x1200 Dell LCD.(Edit)

What is your PSU? brand? model? Monitor resolution?
In terms of value the 5850 is probably the best bang you can get for your buck but that is $50 out of your price range. The 5770 has more value, it performs slower than the 5830 but cost a whole lot less.
