This is a very quick tip for anyone who, like me, has found Visual Studio 2010 to be painfully slow.
Tools ==> Options ==> Environment ==> General ==> Visual Experience
Automatically adjust visual experience based on client performance
Use graphics hardware acceleration if available
No promises that this will work for you - but the difference it made for me was VAST!!!
For information, I'm running VS2010 Pro SP1 on W7 Pro SP1 x64 / AMD 2GHz dual core / 6GB RAM on an ASUS M2NPV-MX motherboard (with integrated NVidia GeForce 6150 graphics) - and everything patched / up to date with latest drivers etc.
With graphics hardware acceleration turned on the editor just clunked - it could take seconds for the screen to catch up with cursor movement / scrolling / typing - with it turned off I'm back to a nice responsive environment.
Hope this helps someone out there!
