I'm new to the forums and wanted some feed back. I'm looking to buy a new HP Pavillion. Basically I'm trying to decide between the d5200t with the Q9650 and the m9600t with the i7-940. I can upgrade the Q9650 from 2.63 Ghz to a 3.00 GHz for $100 and to upgrade the i7-940 from 2.63 to 2.83 it's $400. Is it really worth it?
