Can someone explain chipsets and SLI?

Does the motherboard chipset affect SLI performance? I have an nforce 570 chipset running 2 8800gt in SLI, and am seeing modest performance gains.

For example in 3dmark06 I go from ~10k with 1 8800gt to 11,300 with 2. I realize that at default 3dmark settings my CPU will hold me back substantially, but running the test at 1920x1200 I get 10,800 in SLI, anyone know if that's appropriate? My CPU score is 2300.

In Half Life 2 I get about a 7-10 fps boost on average, but also lower lows and higher highs.

I'm running forceware 169.02, windows XP sp2 32-bit.
 
I should've specified Half Life 2 Episode 2:
1920x1200, all settings maxed out, with 8x MSAA, and 16xAF.
 
There's nothing wrong with your motherboard and the HL2 engine scales really well with SLI (I've observed up to 80% boost). Try uninstalling the driver, cleaning with driver cleaner, and loading the latest (169.09 I think for XP). Don't futz with the game profiles, leave them default.
