Recommended specs?

[Kamikaze92]

What are the recommended specs for upgrading to vista from XP? Currently I have 120gb HD, 3.00GHZ, 512mb RAM, SiS 661FX video card.
Is this enough for vista to run smoothly and efficiently?

I would say you need to stick with winxp. you can find more about vista here (http://www.microsoft.com/windows/products/windowsvista/default.mspx)
and run the microsofts vista advisor will tel you more about how well your system would work.
