I might just do the same when I get mine back (unless I have more bad luck). Would be nice not to see Vantage drop to 1fps or below unlike my lappy lol. Even so, I've just completed wiping the board with my 8600M GT in combination with w7.64, 4Gb of better ram, and my E7500 all running on a modded C90s and Nvidia bios. I managed 50 pts mre than the previous guy which is pretty good considering the points actually scored.
For some reason, my GPU clocked a lot better at different CPU fsb, so I know that certain values do not play well with certain pcie clocks. I could spend time fine tuning pci too, but for what it's worth, I'm happy with my laptop's performance overall now. Particularly now I know the CPU is stable at 3.2GHz+ in my lappy.

Anyhow, that's 2 more points for xs like you asked lol.
