You have two choices when evaluating which next-generation card to purchase. Firstly, given a budget of around £300, you must choose between ATI's Radeon X800 PRO and NVIDIA's GeForce 6800 GT. The bottom line is that you cannot make a bad choice; both cards are excellent performers. Secondly, should you wish to go with a GeForce 6800 GT you need to decide which partner's card is best. AOpen makes a strong case. Its cards are backed up by a 2-year warranty, are priced attractively in relation to others, and include a couple of retail games, too.
