720p on a 15" is similar to the same density as 1080p on a 23", it's not really that bad. As for performance, how is this considered bad? 33 FPS on medium on Metro 2033? This is for a $550 laptop, insane performance. You can get something with discrete graphics, but why bother for the extra 30% in performance for +$150? Any bigger gain and you're in upper-midrange - gaming laptop territory. And even then, you'll need a 560M or 650M, and performance at 1080p with those won't be much better than Trinity at 1366x768.

You can verify just as much. A10-4600M almost matches the 540M from last year (note- this is what an M11x has), ties the 6630M, which is in the Vaio SA ($900 ultraportable). No head-to-head 1366x768 vs. 1920x1080 comparisons, but it's pretty clear you won't get much higher framerates with a
Nvidia 650M at 1080p. Not to mention, even if Crossfiring with a 7670M only adds 20-30% over the 7670M, you're very close to 560M performance in a $650-700 system.
