![]() ![]() The results were so low that GameSpot didn't even try Crysis in its even more demanding DirectX 10 mode. On this test, we were disappointed to see that none of the cards or combinations of cards tested by our friends at GameSpot achieved an average frame rate of 60 frames per second. You may also need to factor in the cost of an SLI-capable motherboard, which can range from $60 to $200 or more. If you're not also in the market for a display upgrade, shop carefully and you can get two 8800 GT cards for less than $400. The full benefits of all that graphics processing capability might not necessarily kick in unless you can properly tax it, which can require a 24-inch or higher LCD that supports those demanding high resolutions. The lesson here is that at lower resolutions, you may see less expensive cards outpace the GeForce 9800GX2. ![]() One minor exception includes Call of Duty 4, where we saw a pair of GeForce 8800 GT cards in SLI mode beat the GeForce 9800GX2 by 9 frames per second on the 1,600x1,200 resolution test. On some tests, the results of which were generously provided by GameSpot, the GeForce 9800GX2 falls where we expected, surpassing both ATI's Radeon HD 3870 X2, the GeForce 8800 GTX. Performancewise, we like what we saw from the GeForce 9800GX2, except on one test. Our Asus card came with a 6-pin-to-8-pin adapter cable (which you might also need, as many power supplies don't have an 8-pin output) that we were able to insert and remove with no trouble. Nvidia's claim is that while it has followed the specification for the 8-pin female end, certain power supply vendors have not built their 8-pin plugs to spec. Our colleagues at GameSpot reported that they broke the plastic housing on their XFX card while trying to unplug the 8-pin connector. The 8-pin connection in particular might cause you some grief. ![]() That's correct, a single GeForce 9800GX2 requires two power supply inputs, whether you overclock it or not. Also of note, the 9800GX2 requires both a 6-pin and 8-pin internal connection to that power supply. Let alone 850 watts, a 580-watt power supply goes well beyond what you typically find in an off-the-shelf desktop. ![]() This includes a power supply rated to a minimum of 580 watts, or 850 watts for two GX2s in SLI, quad-chip mode (for which Nvidia is still working on software support). The second assumption is that you have a robust enough computer to handle this new card. ![]()
