XPmode in Win7 has had terrible performance for me on my new Lenovo T500 with P8700 cpu. Bad delays even just typing text into notepad. My reason for trying Win7, but now have gone back to XP fulltime.

AFAIK, all AMD CPU have virtualization cept the Semprons. With Intel its a crapshoot, with even the same processor model numbers sometimes having it, sometimes not. You have to look at- I think- the "packaging ID" of the CPU to be sure. I notice Dell now mentions "VT" on their systems when they have it.
