Gaming in double-time

Innovision's latest frame pusher, the GeForce 7950GX2 is actually two slightly modified NVIDIA 7900s combined together in an SLI configuration, but only takes up as much space as a GeForce 7900GTX. Not only that, the SLI bridge is built-in, so the card only requires a single PCI-E slot, rather than a special SLI-ready motherboard. The card has 1GB of DDR3 RAM and a 512-bit memory bus, giving you 512MB of RAM with a 256-bit memory bus for each GPU. In 3DMark, GX2 scored an impressive 7903, while the rival cards from ASUS (the X1900XTX) and Gigabyte (the 7900GTX) scored 6314 and 6275, respectively.

The GX2 core has been scaled up a notch to 500MHz, a 30MHz buffer over its 7900GT cousin, while the memory clock speed remains on par at 600MHz.

While noise isn't a serious problem, heat dissipation may be. Even after periods of idle time with no 3-D rendering, the heat sinks were scorching. So overclocking is not recommended unless you have some serious cooling and you'll want to make sure there's plenty of air flow is needed, even during normal usage.

Verdict: For the best performance from a single-slot configuration, you can't overlook this card. However, most current games run fine on less expensive models, so holding out for the next generation of DirectX 10 compliant cards with true Vista functionality might be better in the long term.
