Hmm, stretching my memory to remember and too lazy to Google, but I *believe* the X5690 is equivalent to an i7 990X. So it was a pretty sweet processor for its time, but it *is* nearly 5 years old.

It's kind of a tough call. You'll need to do some research to ensure you're getting the best bang for your buck.
