PCPerspective take a look at the BFG GeForce 7900 GTX OC. Not only is the 7900 GTX OC one of the fastest cards around, it is backed by one of the best lifetime warranties anywhere.

The BFG 7900 GTX OC maintains a small, but consistent performance lead over the reference scores we saw from the sample NVIDIA sent us last month. The 670/820 MHz on the core and memory clocks brought with them around a 3% gain in overall performance. The higher your resolution and the more eye candy you turn on, the better, and we even saw some games like BF2 show as much as 11% performance improvement thanks in large part to the 100 FPS top out of the engine.

If you are comparing the top NVIDIA GPUs against the top from the red team, the X1900 XTX, you'll find that both GPUs share performance leads back and forth in our initial 7900 series preview from last month. BFG's and other NVIDIA AIC's overclocked cards should therefore increase any leads NVIDIA held before and help alleviate any performance gains that ATI had. This is the one advantage that NVIDIA has with enabling their partners to OC their chips.

If you are looking for the ultimate gaming experience, you simply can't beat pairing a couple of these 7900 GTX OCs in SLI mode and pushing your resolutions and gaming to the next level. Besides the obvious performance benefits that doulbing your GPU horsepower gets you, the SLI platform has become incredibly mature over the last two years and offers certain features and aspects that ATI's much newer CrossFire can't quite yet. First, you can get NF4 SLI X16 and NF4 SLI motherboards from quite a few vendors, the motherboards are more stable and their other features (non-GPU based) are usually better performing and higher in reliability. Currently the XPress 3200 chipset for ATI's CrossFire platform is only available from a single motherboard manufacturer, though this will change later this month. If you are looking for stability, options in pricing and features and more robust game support then SLI is still the better multi-GPU solution.
