Recently I have been having problems with my Radeon X1950 356mb GPU, so was thinking of upgrading it if only a little. I only really play wow and pro ev so not much to strain the machine I would have thought but I am quite clueless to be honest.
My build is, Core Dou at 2.66GHz with Asus P5KE motherboard,
600W PSU, running windows XP.
This was my first attempt at a build a few years ago.
I was thinking of possibly the nVidia GeForce 9800 GT as recommended on the budget cards topic.
Hmm UK prices are more or less a gouge but we all know who to blame but going second hand isn't a bad idea. You can land a fairly decent card in the price range such as a 9600gt or a 3870 which was a good upgrade over my x1900xt. Start looking around locally for shops that price fairly well and some eBay sellers do ship overseas which I have done my self.
^Gotta agree there, for the price, that 4850 is hands down the best card mentioned, a 9800GT is not a bad choice either. Everything else mentioned is cheap enough, but really dated.
9600 is a really slow card compared, and a 3870, wow now there is trip down memory lane, not a lot better than your 1950. (well it is, but I still wouldn't want it) You have enough processor power to do better than these relics.
