There are lots of different graphics cards on the market, but they all use basically the same chipsets, I think most use Nvidia or Radeon, your best bet is to go to gaming forums if your wanting a gaming card, I used to sell cards for silly money to people who are only going to surf the net or play basic games, so dont get caught up in the "Ive got to buy the best" nonsense. I used to sell Sparkle, Asus, Radeon and a few others. Most people used to avoid the radeon chip and go for the geforce, I use a 1gb GeFroce 8500 gt and I cant fault it, I also run it at max resolution 1680 x 1050 and it works perfectly. You can buy these cards for about �40 to �50. As far as your old card is concerned Im afraid its either the bin or e bay!
