I'm just afraid to answer ANY post that has to do with the Radeon 9000.............
You know - once bitten, twice shy.. :frown:
I'd go with the 9000 over the MX440. 460 is a bit tougher.... the 9000 is probably better in overall image quality, the MX440/460 will have better AA (not AF)
They're both good choices either way. 9000 will get you a better 3DMark score because it's DX8 compliant.
