Simonta,
Yes I have run the expeience test & it comes out at 4.6 as it has from day one with the betas from 6956 or was it 6596, I forget.
I'm not complaining, I like 7 a great deal, particularly more than Vista & I liked Vista when that arrived, I suppose because I've built my machines around the spec, so they've always been up to the job.
The 4.6 score always highlights my 8500gt gpu as the weak link, but I don't use the box for games, so I'm happy enough with the score, but it is noticeably slower than the six or seven beta builds that I pinched off the net (sorry MS, couldn't help myself).
I only make an observation based on personal experience, but now I have my bought & paid for copy, I wouldn't hesitate from recommending it to anyone considering an upgrade. It is a good operating system,
P.s., it wasn't me who suggested changes at the code level.
