Hey Patrick...just saw in your other thread that you are unfortunately back to your 1000 pound budget. (I don't have that little symbol for pounds on my system unfortunately) I don't think you should rule out one of the lower level AR's though...I found this one, the AR11B, for 1052 pounds

The GO 7600 is a pretty decent card too...and don't forget that native resolution is 1440x900 on the B vs. 1920x1200 on the S...so running games at native resolution might even be easier with the B model. I originally wanted the WUXGA over the WXGA+, but after using it for awhile, i'm glad I got the WXGA+.
