Ok, so it seems that the AMD HD4870 is the way to go for my next graphics card, but I'm wondering if it might be worth holding off for the release of the x2? I'm gaming at 1680*1050, but with a second monitor at 1440*900 for websurfing and all that jazz.
Currently running an 8800GTS 640Mb, so I can hold out for another month or so (rumour has it that the x2 is launching mid-late August if what I've read is to be believed) but I have oey burning a hole in my pocket now
