errm no wut the hell r u smoking, the 7600 gs is worlds faster and better then the 6600 gt 128mb, the desktop wont even run it, look patch 1.2 is comming withen 2 weeks or so, so i suggest get the laptop.
1. portable, much uses for portability,
2. its specs are excellent enough for sh4 meaning u might get high graphics but med-high wud be better not high and not med.
3.its a laptop much MUCH faster then that desktop.
that 6600 gt will be beggin u not to run sh4 it wont handle it on medium graphics, go for the laptop if u want portability, and performance, patch is coming out within the next 2 weeks, and im pretty sure they are going to fix the resoulution bug in the next one.
