if you have any dreams of upgrading your current rig, I'd go return that purchase immediately. If you don't mind chucking your CPU and mobo when you upgrade, then go for it, cause performance is a bit better on socket 754 for your money. As for the idea of upgrading to a 3700, that's not exactly a wise investment - buying a CPU all over again for an extra 200MHz, or 512KB cache, depending on model? I'll pass. With 754, you get what you pay for, and that's great performance, but not an upgrade path, especially not when you buy the second highest CPU grade that will ever be released on a platform. It's liek buying a Socket A 3000+ and looking forward to an upgrade.
