Confusing but, basic. Which is the top performer for AA/Antiscropic Filtering programs, NOT ONLY DX9 (I know the Ti4200 is weak in those areas):

Ti4200 8x 128Mb
FX 5600 128Mb
FX 5600 256Mb
FX 5600 Ultra 128Mb
FX 5600 Ultra 256Mb (does it exist?)
Radeon 9500 Pro 126Mb

From what I've read, the Ti4200 beats the 5600, the 5600 Ultra beats the Radeon 9500 Pro and the Ti4200; but where does the 5600 256Mb stand?
