I just noticed in the reviews on here that the 512mb version has quite a bit better frame rates than the 256mb version. Even more so at the higher res'. I suppose that is because of the newer games having quite large textures. IMO 256mb isn't enough if you are gaming higher than 1024..
Also I gather you are thinking of getting one from umart, but stonebridge have the his version for around $15 cheaper.?? just a FYI
