Well I've been agonizing over building this PC with the hardest bit being what graphics card to buy and where to buy it from. I finally settled on an ATI Radeon 9700 Pro which I managed to buy off Ebay for only £114. Seems like a pretty good deal. If you check out Tom's Hardware VGA Charts, its rated quite high and I got it for less than most 9600XT cards go for. Just need to stick a Zalman VGA heatpipe on it and I'm set. Ebay seems like a really good place to pick up video cards. As power gamers upgrade to the latest and greatest hardware, you can pick up their seconds for pretty cheap. The GeForce4 Ti4xxx cards are going for cheap and they're really decent cards.
This is the first time I've used ebay intensely. Lost a few auctions before winning this one but didn't have to start using sniping software. I was tempted to sign up with Phantom Bidder.
