It's an ITX system mainly just for downloading and HTPC use but i use it for daily use like internet, some photo editing. As for lfs it's below par but it really depends on what res you use.
Netbook would be 1024x600 (or at best 1280x720). Can it do full (demo) grid (12 cars) BL1/XFG+XRG mixed without major hiccups? Preferably with 4xAA or so
