Will upgrade system some time, I've been looking around for more graphics cards and have narrowed it down to these... I think.

I've read an article that the 7900GS can overclock much more than the X1950.

Both of these are about £35 or so more than the 7600GT but they both have Zalman fans anyway which would save me having to buy one separately.

Simple question, from a purely gaming perspective which one do I go for?

cheers.

If your looking at building a smoking gaming rig then go for the 7900GS and SLI it.
