I had pre-ordered my copy of Windows 7 Home Premium 64 bit and I must say I am impressed!

I backed up my documents and other stuff and did a fresh install and WOW!
On the RC 7100 in the windows experience index was higher on a few items than in Vista.
But on the actual
Windows 7 Home Premium 64 bit version the ratings were even better: Processor:========> 7.3 Memory (RAM):====> 7.4 Graphics:=========> 6.8 Gaming Graphics:===> 6.8 Primary hard disk:===> 5.9 (this was the only one that was not better!) On Vista all were 5.9 and on the RC only the top 2 were 7.3 with the rest 5.9 Woot!
