Need laptop purchase advice please

[ukebec]

I am considering buying a laptop Sunday.

Intel Pentium T4200 Processor
3072MB DDR2 Memory
2 total memory slots
Maximum memory expansion 4096MB
Intel Graphics Media Accellerator 4500M(shared) with up to 1309 MB graphics memory
802.11 b/g WLAN
250GB Hard drive

My concern - will I be able to play POTCO on this reasonably? I mean without insane lag (relative to what we all already experience).

Thank you in advance for any help you can give me.
