Re: Alienware m14x r1 question?
That i5 isn't that old... It's a 2nd gen which is still fairly decent.
As for upgrading to an i7... that I'm not sure. I couldn't find much on google in terms of other people upgrading the CPU to an i7. Even if you did, mobile chips are much more expensive than their desktop counterparts, so you'd have to either shell out big bucks, or find a used one that would work with your system.
I did see a few things about upgrading to an R2 motherboard, but not much else was said other than some people were thinking it was possible. Whether it would actually fit or not, is another question entirely.
As for the lag in WoW... what are your temps while idle/load for your GPU/CPU? Have you tried updating your GPU drivers from nVidia or AMD (depending on what kind of GPU you have in the laptop)? Post your temps for idle/load and lets see what we're working with.
