The jumper adds novelty, but ultimately this card is outperformed by the competition. Worth considering for a budget system but not much else.

It's a little cheaper than comparable cards, but its performance is not quite up to scratch.

Even if you're anxious to salvage your investment in a high-end ATI Radeon 800-series card, at this point we just can't recommend the expense and hassle of moving to CrossFire. If you crave maximum graphics performance and resolution then a card based on NVIDIA's GeForce 7800GTX is your best bet. That said, we're not ready to cross out CrossFire altogether, as the technology could prove more exciting paired with ATI's next-generation cards, which should be shipping by the time you read this.

If you don't play high end games, then the PowerColor X1900XTX isn't for you. For serious gamers it could be a worthwhile purchase, though an expensive one.

Although this card is expensive, it's still an excellent component for any enthusiast's computer. If price isn't so much of an issue, but enough to not warrant purchasing an 8800, this may very well suit your needs.

The Sapphire Radeon X1650 Pro isn't the hottest card on the market, but it's a good budget card if you won't be playing the latest games. The X1650 Pro has been Windows Vista certified and will let you run the Aero interface in Windows Vista.

The Asus EAX1650XT is a good budget option for a Vista upgrade or simply to give new life to a gaming machine while cards supporting DirectX 10 trickle into the market.

A well-built card with some scope for overclocking that is suitable for gaming at a resolution of 1280 x 1024. It will provide its smoothest results at this resolution, but it may struggle at higher settings.

The ATI Radeon X1650XT GPU in this HIS card is on steroids and will provide good performance for most current games. It's a good stop-gap solution if you need a new mid-range graphics card, but don't have the patience to wait until DirectX 10-capable ones are released.

The ASUS EN8800GTX AQUATANK didn't produce stellar results in our tests and so we recommend buying ASUS' regular non-water cooled 768MB GTX instead, which will leave enough room in a PC case for an SLI solution, too.

The MSI NX8500GT can be summed up as an inexpensive card that's perfect for an entry-level Windows Vista PC, or a media centre PC, but it shouldn't be considered if you want to play current and future games.

Overall, the EN8600GT, with the OC Gear module, offers a convenient way to overclock and monitor your card's performance, but it costs $50 more than ASUS' regular EN8600GT graphics card. The extra cost, and only very slight performance advantages when overclocking, mean it's worth sticking to the regular EN8600GT instead
