I am planning to buy a laptop & can choose the processor. I am an “average” user: Firefox browser, OpenOffice (spreadsheet & word processing mostly), email, FaceBook, occasional YouTube, some radio streaming or listening to CDs, websurfing & online shopping… no programming or gaming or anything advanced like that. Will be running Windows 7. Will have 4GB Shared Dual Channel DDR2 at 800MHz memory. Will have an Integrated 1.3 MP Webcam & WiFi card & 8X CD/DVD Burner. Processor choices are Intel Pentium Dual Core T4300 (2.1GHz/800MHz FSB/1MB) or Intel® Core™2 Duo T6600 (2.2GHz /800MHz FSB / 2MB) or Intel® Core™2 Duo P7450 (2.13GHz /1066MHz FSB / 3MB).

Considering the type of things I would use it for, would the 2.1GHz/800MHz FSB/1MB be sufficient for multitasking with multiple windows open?

Thanks very much!
