After browsing around a lot I actually dropped the idea of getting the VAIO, and the ASUS option springs up to mind.
For 1750$ I get:
Q9000, 260M GTX, 4GB DDR2, 640GB 7200 and BD-ROM
or for 1500$
T9600, 260M GTX, 4GB DDR2, 320GB 7200 and no BD-ROM (which i can get from ebay for extra 200, which makes the price the same)
so it's to the ultimate question: a fast 2.8 dual core? or a sluggish 2.0 quad core?
since i'm not rendering anything and just using this for games (not necessarily the top end ones), movies and internet fun, which is better for my using profile?
