My laptop's hard drive just died. I'm looking to buy another. For multi-tasking which is better? Core 2 duo 5450 or AMD Turion 64 x2 tl-60? The amd also has a separate graphics card. Specs would be core 2 duo T5450 with 250gb hd 2gb ram, 15.4" screen, integrated graphics, or Amd turion 64 x2 TL-60, with 200gb hd, 2gb ram, 17" screen, discreet graphics card. Please help, I'm in a hurry. Thanks
