Better would be 7040tx, just for NORMAL use..
If you want a decent gaming performance from your laptop, then 6165tx's 6770m AMD will beat Nvidia 630m all hands down.
Benchmarks:Nvidia GT 630mAMD 6770m
Remember, 3rd Gen processors are just 10% faster than 2nd gen, but alot cooler, and in i7, you won't notice performance difference in both...
So, choose wisely, i'll say 6165tx, as i'm into alot of gaming..
