I recently purchased a laptop as some of you may know. The laptop came with VISTA Home
Premium SP2
I was also promised a
free upgrade disk for Windows 7. I had my doubts but the Windows 7 CD arrived as promised, & rather then put the upgrade in my laptop, which already had Vista Premium SP2, I decided to upgrade my Carl AS ROCK

Weathers Core 2 Duo HD3850
AGP 
Desktop instead. Since getting the laptop, I felt Vista was faster and smoother then XP and so I was ready to bring AGP into the modern era.
The system upgraded
FLAWLESSLY and Carl AS ROCK Weathers is running 1000% times better under Windows 7 vs XP, however I really can't tell much of a difference between the feel and performance of Vista SP2 on the laptop and Windows 7 on the desktop.
For reference, the Laptop has 3 gigs of memory and a 350 gig hd vs 2 gigs memory and 280 gig HD on the desktop. The desktop has much better video, and slightly better processor but both are
POWERFUL and
DUAL CORE.
I also read an article stating the when benchmarking XP, Vista sp2 and Windows 7, Windows 7 and Vista SP2 were fairly equal and both blew XP Pro SP3 out of the water. From my own experience I would say this is correct and recommend Windows 7 upgrade if your running XP, but not so much if your have the now
GRIZZLED SP2 version of Vista.
I would also like to say that Windows 7 rated my
512mb HD 3850
APG system experience as
7.1 which clearly demonstrates the
DOMINANCE.
