Ask about upgrading RAM as well. Also, what is the storage capacity? HD takes up alot of space. | Report abuse Maziar CPUs Authority November 20, 2010 6:36:23 AM Welcome to the forums! I just checked Dell's website,and you have to pay extra $325 for 840QM which isn't worth it at all(because its slightly faster),so stick with 740QM | Report abuse Fareed Massood November 25, 2010 9:05:14 PM dogman_1234 said:I would say any of the i7 8xx series would do good.
