"I am however, very interested in a converted Server 2008 to Workstation because from what people have said, it is what vista should have been." Actually, this is entirely incorrect and doesn't make a lot of sense... Vista and Windows Server 2008 are fundamentally EXACTLY the same (minus the obvious server/client specific features and componentry that makes sense in each context - the core OS is the same OS. The differences are in tuning, security policy and shell for the most part - yes, server core is a server-only construct as are other server-related components and features - but, again......., they are fundamentally the same......). I don't understand this "Windows Server 2008 on the client" nonsense. It's a server OS, built for serving. Again, it is VERY similar to Vista architecturally. In fact, Vista and 2008 come from the same sources......C
ENd of last year I built high end desktop and decided to have vista ultimate 64 on it. In start i not felt much issues cause i not have direct comparision to 32 bit vista. Now as i getting more familiar i feel my system performs slow compare to 32 bit vista OS. Boot time is also slower 64 bit. Apart from that i get issues with application compatibility on 64 bit. Just recently i really felt that i made mistake by having 64 bit when i found lot of media center plugins are not ready for 64 bit specially recently Tv Tonic have a NBC Olympics plugin for vista media center only for 32 bit. Few days back i was reading on channel 9 or channel 8 about Microsoft's new utility called steadystate. I was excited with its features and to my disappointment that too was only for 32 bit.So now after having 64 bit for more than 6 months i feel like only advantage i've got is having more than 3gb RAM. How can I expect 3rd party apps compatible with 64 bit when some of Microsoft's own apps are not ready for 64 bit.
I must point out here, that the signed driver requirement does not equal a WHQL requirement. Third party verified certification will suffice, which in your example would be a nvidia certificate. Modified inf files do not invalidate that type of signature on a device driver.
