From what i have read it should be able to use any radeon based cards although im not sure about the 9000 or 9700. i myself bought a hercules radeon 128meg 8500 le a slightly slower version of the 8500.radeon 7000 is a budget card and i have seen these for 40 pound and lower, the radeon 8500 should be cheaper now because it is being phased out by the radeon 9000 the 8500 i have will hopefully be ok. weather it makes a difrence being ati or another maker im not sure but because all radeon cards use the same pc drivers i cant see make being important. :-)
