It's come the time of year where I upgrade my gaming PC and I'm looking at changing my graphics card. I currently have an ATI 4870 running at 1680x1050 and I've got about £200 to spend. So far, I've been looking at the ATI 5870. I know it's a generation behind now, but it's still quicker than everything else in the £200 price bracket, such as the 6870. Is the GTX 560 likely to be any faster than the 5870 as I believe that will be around £200 too? Any opinions?
