PS 7 is What I use at work… It's pretty much just as good, the downside for me is that you can never move the image outside the canvas/screen border… So that's pretty much the same as what you're stuck with now in the CS4 navigation tool.

Upping the number of cache levels to 8 improved the brush speed issue a lot. Still not as good as CS2 and 3 though. Man… Having a fast Quad core with plenty of ram and a high-end video card still doesn't matter… :(
Looks like I'll have to get the 64 bit version of Vista and yet more ram… :(
I never used anything newer than 7. Would be insane to try having only 512mb memory, haha.
