Well, when I run ANY kind of benchmark, I set to Windows Classic, no themes, no wallpaper, PLAIN. I also shut down all of the "useless" services, such as any for power management, my Firewall, anti-virus, etc. as I won't be needing those when running benchmarks anyways. I also use Notebook Hardware Control to force my CPU to run at 2.00GHz at ALL TIMES, that way, it doesn't decide to throttle or something when I'm benching (though it's unlikely, it's better to have all of the bases covered). That's probably how I got a better score than you did with the same clock speeds

. Don't worry about it though, as 200 points really isn't all that much in the big scheme of things, now 1000 points or more, and I'd be wondering


.
And as I've said before, the XTreme-G Drivers have (lately, at least) favored Image Quality over performance, meaning that they give better Image Quality at a little-to-no loss in performance.
And as I was saying a while back, I've been toying with the idea of 2 versions of the driver. One for ultimate performance (as best as a driver can accomplish, of course), and one for best Image Quality (essentially the same thing that has been released)
