The 260's are fucking great graphics cards, and a lot lot better than the 4870 in real terms but they will come down in price hugely in the next 3 months as Nvidia and ATI are both bringing out new GPU's.
The 260 will come down to around £140 by then I recon.
you reckon they'll be as cheap as that???
I know there's the 55nm chips out in Jan but i wasn't expecting them to drop in price by almost £100
