Looks like my 4870 has bitten the dust; not been that happy with the drivers, and with it only last 2 years I'll probably go back to NVidia. What's the best buys around £200 at the moment? In particular 275 vs 285 and the 896/1792 & 1Gb/2Gb divides - is the 285 and.or the extra memory worth it? And why do they all come with Batman?
