What do I really need to run Windows Vista ? 
Slow Machine:
1. Single Core CPU
2. 1GB of Ram
3. Intergrated Video
Runs OK if you disable most of the hard drive thrashing features.
Mid Grade Machine:
1. Dual Core CPU
2. 2GB of Ram
3. An actual video Card $50+
What most people get when they buy a computer today (except many come with intergrated video card).
Fast Machine:
1. Quad Core CPU
2. 8GB of Ram
3. Video Card $150+
4. Vista 64 bit Edition
Most don’t need quad core and 8 gigs of Ram but it really makes Vista 64 run like WinXP with 2GB.
