Web development on a super fast machine... Pros/Cons, Testing for slower systems
I'm not even sure that such question is for StackOverflow, but that's the only good place that I know for asking this stuff, so I apologize in advance and I hope that it'll be useful for others as well.

I am sick of working on a computer that does not always bring me Intellisense on time, that takes a long time to switch between open windows (like to check e-mail, or sneak into facebook for a second, or switch to Photoshop CS5 from Visual Studio) - in short, a computer that is delaying my professional work and reducing my productivity... Until something opens I could even forget why I clicked that thing...

And it doesn't matter what kind of a computer I have at the moment, but my question is the following - If I'd build a very expensive, beast desktop machine with latest tech that is available today - I know for certain that it will be up to 20 times faster than any of our web-servers... - ie, "Production" environment... 

I can see already that I might be very disappointed in observing my web sites, web applications performing slower than on my development machine, etc..

Has any of you met with such problems ? 
Is there any way to simulate a slower environment (some Virtualization trick) ?
