I'd get THIS CARD:http://www.newegg.com/Product/Product.aspx?Item=N82E16814102993
It runs at 1100MHz (most at 1000MHz) and costs $115 (after MIR) but has free shipping.
Sapphire is also a great company for quality.
*Also, learn to use the free tool RadeonPro for:
a) forcing VSYNC when unsupported in a game (i.e. Witcher #1, drag the "witcher.exe" file into RadeonPro and enable VSYNC.. )
b) forcing Anti-Aliasing when unsupported in a game (ME1, however in the case of ME1 I'd use SuperSampling instead of MSAA. More costly but worth it.)
It has other features but those are the main two. The CCC (Catalyst Control Panel) may offer some of this functionality though I'm not up to date on that (NVidia now).
