Upgrading now is not a good idea
Sandy Bridge is nearly here
LOL @ The cases made of razor blades comment - that seemed to be the true not many years ago, nevermind back in the 486 days.
I hated those horrible heatsinks that had the stubborn clips where you'd end up using a screwdriver to fit them on - I ended up with dried blood on my mobo thanks to a careless slip there.

Hrm not a good idea? I suppose worst case, I can hang on til Feb/March. Just getting the upgrade "itch" is all.
