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
