Hey, I can tell you I loved that notebook until it messed up. It is a little fragile I think, due to the build construction, but for the price it is hard to beat. Both of mine actually came with a i5 480M, which was the next processor up from what was advertised.
I had LCD problems with the first system, and a keyboard issue with the second system. I didn't opt to get a 3rd sent to me, and just requested a refund.
It did play modern warfare 2 fine. The GPU is middle of the road, nothing spectactular. I would say you should be able to play a lot of newer games with at least low settings, possibly medium depending on the game.
Overall, the laptop's hardware is well paired with each other, there shouldn't really be any components that bottleneck the other.
I wouldn't recommend to get this laptop though, just from my personal experiences. I'm sure there are plenty of owners out there who've had good experiences, but I had 2 back to back that had hardware problems, and they were both brand new in the box. Thankfully, Amazon's return policy pretty much rocks, they paid for shipping since it was under 30 days, AND cross shipped replacements.
