windows vista results

Hi,
Fist here is my system: Athlon64 3200, 1gb ram 1 SATA Raptor (1000RPM) 36Gb used for system installation 2 SATA (1x160, 1x 250) 2 ATA (1x200, 1x40) Screen ACER 17" TFT Geforce 6600 GT
my VISTA Test: buned the 2 dvd (32 bit & 64 bits). None of them managed to finish setup properly (tried and sucessfull on another system so DVDs are fine) using a (sic) linux loader I managed to get access and boot Vista. Windows was very slow and I had a very annoying black screen for about 1/2 second when receiving security warnings. Though it as due to the display driver. I installed the required Nvidia driver, rebooted. Overall the system is running better with no more delay for the security warning. I noticed that it was already downloading an update so I selected shutdown and install updates (as I had to go). Very weird display at this point. I had the nice aero glass desktop screen with message, "do not power off " with a lot of cryptic text (I presume some comments on the updates going on but couldn't read). Once finished Vista shutdown expectedly. I like the new nice look, the popup effect when opening programs... everything seems a lot nicer and more thought and more user friendly (except the annoying security warning), all nice and all. The only ONE thing that annoyed most of all is that aero is supposed to take advantage of the graphic card to managed the display.... what I see is that it takes up to 10% CPU (yes CPU not GPU) just to move a window about ??? Am I missing something here ? is there some hidden tweaking to be done to have aero behave the way it should ? Plus the overall system is about twice as slow as the same system under XP. This is already one of the reasons I chose to wipe my XP and install Vista on the Raptor...
Just for the sake of testing, I installed one linux equivalent to vista : OpenSuse 10.1 featuring the Xgl feature. appart for the necessary manual configuration to have Xgl working (for those who know, Xgl is the linux pendant of the Aero glass (or should I note it the other way around ??)). This system works like lightning compared to Aero, I've never seen my system run so smoothly. Plus Vista could really take benefit at watching what Xgl does, you can see windows wobbling aroung when moving them, make them transparent in a breeze, the task swithing shows "live" thumbnail of the application... Oh! and of course, CPU never went higher than 1%, and that was when opening Openoffice... didn't move at all when playing with the windows...
I think I will simply revert to XP until Vista is a little optimized. Take a real look at Xgl and what it can do... there is still some months to tweak Vista up to its promises... until then...
