I've got an M65,
NVIDIA Quadro FX 350M 256MB
T2300 @ 1.66GHz
1.00 GB Ram (667MHz)
I can run BF2 with most settings in medium (except the dynamic stuff) without a problem. BF2SF runs also, but you can feel the Ltop overloading a bit more. Regarding Mods, I run Project Reality, all in low and its ok.
Crash to desktops will ocurr every now and then.
If you are not going to use the graphic card for workstation programs and just for gaming, get a gaming card, dont go for a workstation one unless you get a really really good one.
Hope this helps mate.
