I appreciate your response, but as I said before, this "netbook" (I wouldn't classify it as such) handles every game I've thrown at it - including other "CPU-heavy" games - and it has performed admirably. I think the problem I'm having is mostly memory-leak driven, but it could also just be poorly optimized. You don't sound terribly familiar with the M11x, but you should know that it performs incredibly well on every game I've ever played on it. Period.
You may classify it as a "netbook", but it has garnered a lot of respect for being much, much more than that. It's a gaming computer that handles many, many modern games at or near their highest specs and DOES NOT SLOW DOWN. This game should not be doing this. I'm certain.
/end rant.
Try supreme commander 1 lately? With the bigger games of that your computer would crawl slower than a newborn.
Out of all the games you listed (Crysis, Empire: Total War, Starcraft 2, Borderlands, Fallout 3, Dragon Age) only Empire:Total War is somewhat CPU intensive. Though with the settings turned down it is manageable. Crysis is GPU limited usually, as far as I know the others are mostly GPU intensive.
Your laptop has a 1366x768 resolution which is about half the pixels to render as a normal 24" monitor (1920x1080 is pretty common for those). If you didn't know, resolution matters when it comes to frames per second. A small resolution makes a low power pc perform much better than it appears. In CPU intensive games resolution matters much less for performance. It can literally mean you get double the FPS at 1366x768 than at 1920x1080 in most games, but in a game that cpu is everything your computer will chug.
And like I said in my first post... Brand doesn't matter. A computer is a collection of parts. It costs 1150 to order a basic M11x on their site which includes the 350$ extra for 8gb of ram (lmao...)
For 1150$ I could build a quad core computer that OCs to 4ghz with 6 gigs of ram and has a crossfire 5850 setup which would get at the very least three times the performance your laptop gives. No monitor, but you don't really need crossfire, and those GPUs are 300$ take one out and theres a very good monitor at a reasonable loss in gpu performance. Still would run most of todays games on ultra with just one GPU @ 1080p.
