Default SLI scaling issues

I recently went SLI with my pc, however, when i ran 3Dmark03 on my pc, my score dimished to 20K with SLI from 27K without SLI....

Also, when i ran the crysis benchmark tool (x64), my fps was lower than on single graphics card. I am running forceware 169.25 and i have crysis v1.1 and the custom V High settings...

I havent run 3Dmark06 yet, since i first need to download it, which is no easy task with 512K broadband but i will apprise you of the situation when i finally do.

Anther problem is that my CPU is forced to do all video decoding, so i had to overclock my CPU just so it decoded a H.264 720p file without stutters...

Does anyone have any idea what my problem is and how to rectify it?

Btw, i am running on a fresh install of XP x64, with no addons or service packs except server 2003 sp1 which came with the CD...

please help....i spent a lot of money on this upgrade, and i'd rather it wasnt wasted...

CPU: Intel Core 2 Quad Q9450 @ 3.4GHz
Motherboard: Foxconn Blackops X48
Memory: 8GB DDR3 (1361MHz)
Graphics: ATI 5850 1GB GDDR5
Hard Drives: 1 x 500GB, 1 x 1TB
Case: Antec 900
OS: Server 2008 R2 64bit
