I'm in the UK and that price is STEEP!
You should find a GF3TI200 MUCH closer to £100 (ww.DABS.com and ww.ebuyer.com I have used and rec the former).
I would strongly rec holding on for a few weeks to get hold of a GF4TI4200 as it'll have way better perf than even an o/c GF3TI200 and will be under £150.
I sold my GF2 when the GF4 were announced in Feb and have since been running with my dusty rusty 3dfx Banshee waiting for the GF4TI4200, and finally the end is in sight!
The GF3TI200 is great, but if you can hold on, in less than a month you'll have better perf than both the GF3TI500 and Radeon8500 which were £300 2 months ago.
hope that helps, believe me, I know what it's like.
