I have this old E2180 @3.2 rig with an 8400GS that I and the rest of the family use for web browsing,etc. The 8400GS is fine for what it is, however, this rig will soon be passed down to my sis with an E5200 OCed to 4Ghz. She would like to be able to play SC2 at mid quality (at 1280 or 1680). When I have friends over, I would like to be able to play COD4,Crysis (obviously at low-mid), Halo CE, and some SC2, LOL,etc. I/she would like to spend less than $90 (after MIR). So far I have narrowed it down to a 4850 or a 9800GT.
