Looking for a good laptop

1) Budget: About $2000 + or - $100?

2) Expectations: Um, maybe to be able to connect to an HD TV?, Also I don't want applications to take forever to load, It should also be quiet but that is not much of a priority.

3) Usage: Mostly, I want to be able to play high-end games (for about 3 or 4 years after the purchase) Also I need to use this computer for school work and be able to surf quickly.

4) Questions: I am debating whether or not to get the NVIDIA GeForce GTX 675M 2GB or the AMD Radeon HD 7970M 2GB. Should I just pick up the 675 and wait for the future to upgrade my graphics card in hopes of better ones? Would there be much of a difference between these two graphics cards in terms of graphics? Also, I want to know if the hard drive would make much of a difference in playing games, I am thinking about the 750GB Hybrid 7200RPM with 8GB SSD vs the Intel 120GB SSD (520 Series). I have like 4 TB of back up harddrives to store stuff. Also is the 16Gb memory too much memory? I want to cut costs so I figure here is where I should do it.... Also I want to know if I could extend my warranty after the purchase date. Sorry for so many questions I am not that technically savvy.
