Cheers for the help Duke of Serbia. I had a look at the Gigabyte range. Turns out they don't have an agp x1600 but they do have a nice set of x800's. However trying to find a decent place to purchase them is hard and I still want to stick with the websites i'm used to (though i'm tempted by overclockers.co.uk). I was quite impressed by the passive cooling on the Gigabyte cards, but I imagine that very effective air cooling is required to keep such a powerful card cool and i'm not sure i've got that. If anyone knows which is the better card - x1600 or x850, then I would greatly appreciate the help. I'm hedging by bets on the x1600 as it has shader model 3.0 and HDR, and its newer, but i'm still not entirely sure.
