Well 64 bit machines have been running the x64 version pretty well. 3D modeling software does use quite a chunk. Blender? Or do you have enough money to buy something else?
Anyway, Eon started as my attempt to help out people with 64 bit whose computers don't run Java very well. It's turned into my primary one because there's just so much more I can do with it. I didn't entirely understand your reply though, do you have the x64 version of the timer?
