I'd move up to the 670M - Clevo 170-EM (also had double the RAM). I upgraded ($115) for a 750 GB Hybrid SSD / HD) bringing the total to $1489 ($1569 w/ Windows Home Premium 64 bit) ....equivalent Asus Model (G75VW-RS72) comparably equipped is about $25 more $1594......it's a tossup between the two but if ya going to upgrade the CPU, I'd get the Clevo for the better cooling system.
