Vista SP1 is officially out!
This really is good news, trust me. I installed the update from a standalone package (450MB) and the difference is amazing. You don't even need a benchmark test, the system speeds up heavily.
I have Vista Ultimate with 1GB Ram, Intel Celeron 2.93Ghz and GPU 8500 GT 512 MB. Finally I can feel that my PC is breeding freely. Everythi9ng is faster, the start up, file transfering, opening windows, faster, faster, faster...
