This is off topic, but I'll just say this. You should re-read the review, since the GTX 280, is playing the games at higher resolutions with higher levels of AA and higher levels of in-game details than the 9800 GTX, while sometimes being almost twice as fast in some cases. Also look at the Apples-to-Apples section, where a single GTX 280 is matching or beating a 9800 GTX SLI setup.
It only beats it when using super high resolutions that 90% of the gaming population do not use. When gaming at 1680x1050 or lower it gets beat by 8800gt sli set ups and would probably be close to a 9600gt sli setup which is a lot cheaper.
