Which if these HDs should I get?

I need a new harddrive for my computer. I am looking for something on the performance side and that has quietness. I am looking at the Seagate 80GB 7200.7, and the Western Digital 80GB. Which one would be better?

Newegg has been having sales on the WD 80g, 8mb...lowest was like $59. Its worked very quiet for me. So quiet in fact that the only way I can hear it is if the side case panel is off and my ear if right next to the HD. Im not sure if the seagate has the 8mb cache or not.
