Adobe CS4 seems to run fine and dandy (Photoshop 64bit flies!), though after some fighting with stability of the rig.
The biggest thing that I've done extra and made a decent difference is to ditch the standard Intel cooler on the i7 chip - it simply doesn't do much in keeping the chip cool. For instance, running a heavy stability testing app, Prime95 in blend mode, the chip was running at 78c. After I swapped out the cooler for a better air cooler, the Prime95 test runs at about 50c - and the idle temps are nearly as good - 32c versus 19c with the better cooler.
Windows 7 looks far better than Vista to me, and it can look even prettier if that's your thing - there are loads of cool themes and background pictures to add free from Microsoft's Windows 7 site.
Biggest negative about Windows 7 is that I've had splash out (£40) for Nero 9 Reloaded, to burn disks, rip audio CD's etc. But it's a good app and comes with a free backup app for documents (and recently completed movies) etc.
