Check the following link if you want to see what Microsoft advise for there next version of windows Vista, due out around Jan 2007.
Below are the lowest specs Microsoft recommends, and as always the are the care minimum to run there new opertaing system.
Windows Vista Capable PC includes at least:
- A modern processor (at least 800MHz).
- 512 MB of system memory.
- A graphics processor that is DirectX 9 capable
Personally I feel the min spec needed is:
1 Gig Ram, at least a 2Ghz processor
and a 128meg or 256meg ram graphic card,
SATA hard disk 100 gig.
It will run on what Microsoft suggest, but will be VERY SLOW.
So, if you are buying a new machine, save extra and go for quite a powerful machine and not the cheap budget ones that are around a lot now.
