Visual Studio 2008 Requirments

Question

I found this on msdn2.com:

Minimum: 1.6 GHz CPU, 384 MB RAM, 1024x768 display, 5400 RPM hard drive 

Recommended: 2.2 GHZ or higher CPU, 1024 MB or more RAM, 1280x1024 display, 7200 RPM or higher hard drive
  But if i had a core 2 duo with 2.0 Ghz , i know thats better than single core 2.2 ghz and more ,but is that enough  or would it be good to have a 2.4 core 2 duo ?  and if the harddisk has only 5400rpm(do laptops hardisk run faster than that?)  is that enough for VS2008 to run good ,i mean real good :D
