The HDD isn't that big of a deal (I barely use 200GB on my desktop as it is), so the main thing I'm worried about is the graphics. I read that the only major difference between the two is the VRAM (DDR3 vs GDDR5), and other than that the cores are basically identical. Is GDDR5 a big enough improvement to justify spending the additional $100?
Also, I'm trying to get at least an Ivy Bridge i7 quad and decent graphics for as low a price as possible. If there's another laptop out there for cheaper, let me know.
