I am thinking about getting a laptop(customizing). For the CPU I can't decide between a "Intel® Core™ 2 Duo T6400 (2.00GHz/800Mhz FSB/2MB cache)" or a "Intel® Core™ 2 Duo P8600 (2.40GHz/1066Mhz FSB/3MB cache)". The best video card I can get for this laptop would be a 256MB ATI Mobility Radeon HD 3450. Would I see a difference between the T6400 and P8600 even with that video card? Should I go for the lesser T6400 and save the money if the ATI video card would be the bottleneck?
