I'm hoping to get a new computer fairly soon, and I know what I want for just about everything except the video card. I'm deciding between the X1950 Pro (512 MB) and the X1900 XT (256 MB). Both are between $199 and $220. I thought about an X1950 XT, but it's just a bit too much for me... my monitor's native resolution is 1280 by 1024, and I usually play at that res. Will either of these play Oblivion acceptably? Which is the better buy?
