In Half-Life 2 and Day of Defeat with HDR it's again slightly behind but again the overclocking results pull it ahead, though not by so great a margin as in the other titles. So while the Asus Extreme N7800GT Dual is an achievement technologically, it's slightly disappointing performance wise - unless you overclock it. However, with its ability to do this above and beyond single cards, you'd be mad not to.

Even though you can't use two of them in combination, the Asus Extreme N7800GT Dual would be worth considering if you want to go SLI without the hassle, or the noise, of two cards. The performance is there if you overclock and it is quieter, which always helps you enjoy your games more. The problem is then that at the cheapest price we could find it, it was still more expensive than buying two of the cheapest 7800 GT cards.
