compares with my laptop (intel c2duo p7350 2ghz / win7 / gforce 9600M GT 512mb / 3GB RAM)?
The processor is similar, if I'm not mistaken yours is actually better due to a higher amount of cache memory (noob-ish speaking though). I suppose 3GB of RAM wouldn't be too much trouble, it would be nice to know how fast it is, but generally I think you'd be fine with that.
The main problem is the video card, Geforce 9600M. As far as I know, the notebook version of the card (9600M GT) is quite a bit worse than the desktop version of the card, the 9600GT, which is significantly worse than an 8800GT, which is significantly worse than a 5770.
So you see... D:
