I am building a new machine, in fact i am still tracking the order by ups as we speak, i have ordered vista x64 ultimate for system builders, but i have heard a lot of good things about win 7? any one have any input?
Ignore it. Windows 7 isn't even retail yet so the rumors and speculation over how good or bad it will be aren't reality yet. Your Vista x64 is fine. I would wait at least six months after Windows 7 is out to evaluate it, remember how Vista when it first came out wasn't terribly impressive? Unless you want a system that's potentially unstable, I would stick to non-beta versions of operating systems.
