Toms review Keep in mind that if I remember right, the comparo between the T7600 and T2600 was done before there was an optimized bios. The article also has other links for you to look at the differences..
The basics are the Core2duo is about 20% faster and uses 8% less power than the older architecture...
As for the ram.. it's kinda up to what games you're gonna play. I know Battlefield 2 & 2142 run a lot smoother with 2gigs. With 1 gig, I (and a lot of other people) had massive lag for the first couple minutes in game. Loading times were also sped up.
