Is the 4500MHD really that good? How well would it handle TF2 or L4D (the most taxing games I play)?
Also, where are you seeing this deal? I don't even see Vostros on the Dell site anymore.
Looking for a decent 13" laptop with a dedicated GPU. It doesn't need to be anything fancy, though something like a GeForce 8600M would be better than a 8400M or Radeon HD 3470.
Have you tried overclocking the Atom at all? I've heard tell that someone overclocked it to 2.0GHz without too much of a problem. I don't know if it was just to see if they could or if it was a long-term thing, though.
