'05 Help

[wtkprol]

Hi, Ive been trying to hit 9500 in 05 for a while now. Currently I am running a 4400 @ 2.75 and my eVGA 7800GTX @ 517/1397. If I go any higher on the card my scores go down, and going any higher on the cpu doesnt help scores any. So I am pretty much maxed out as far as mhz goes. My highest score so far is 9497 (yea I know I shouldnt even worry about 3 points but I want em and maybe go higher.) I havent messed with any other things in Rivatuner except for the core and memory mhz. I have run across something called Desktop Lite, its like an simpler shell for Window Explorer with one executive file. (maybe you have heard of it?). Since I have no desire to install Windows 2k, I was wondering if this would improve my score any. If not what tweaks can I make to get it higher? Thanks

btw, I am running HeavyH20's modded bios on my GTX.
