I want the biggest cpu i can get. I have a HP Pavilion A1740N with a 1.86GHz Intel Core 2 Duo (E6300). The MB specs Here: http://h10025.www1.hp.com/ewfrf/wc/...a&lc=en&dlc=en&product=3340229&dlc=en&lang=en tell me i can have a E6x00 CPU, so before i go and spend lots of money, would upgrading to the E6600 or E6700 work and be worth it?
