Interchanging Laptop and Desktop CPUs
« on: April 09, 2011, 01:41:05 PM »
I'm looking into buying an Asus G53JW laptop. When I was customizing it I noticed that it included an Intel® Core™ i7-940XM Extreme processor. While this is still a high-end processor that I think I could live with I would rather have an i7-990x instead. The reason being, the extra 2 cores. While it looks like the two should be interchangeable and I will post the specs for each below, I would like to know if it is actually possible and a smart decision before I go ahead and purchase it.

Why did you  have to tell him?
I wanted to tell him 'just go ahead' and send that poor
Intel® Core™ i7-940XM Processor Extreme Edition   to me!
