I want to buy a new laptop for Gaming and for the Graphics Card are 2 options:

- Nvidia GT650M 2GB DDR3
- Nvidia GT640M 1GB GDDR5

Which is better? Can you notice the improvement on GDDR5?

Thank you very much!!

GT 650M is considerably better than GT 640M. Even the DDR3 version.

Those two card won't be suffice for gaming in my opinion, you better get a desktop pc...

I use only FSX, a processor-based game. The GPU is only for some graphics "things".

"I want to buy a new laptop for Gaming[...]"

I just take it that you want a gaming laptop...so if you want one you either have to spend a lot of money for a decent mobile gpu like the 670mx or 7970m.
And for that you can have a desktop with less than half of the money.

I don't see the difference between the i7 3630QM and the i7 3635QM. I'd go with the cheaper one with the GT 650m.

Pros:
- Blu-ray drive
- JBL speakers
- Better GPU

Cons:
- Heavier
- Smaller battery
