How worthwhile would it be to upgrade now from my current rig (Athlon XP 1700, 768MB PC2100, Nforce2) to maybe a Athlon64 3200 (waiting for the Venice or San Diego)? In the past year or so, I haven't been gaming much at all, but I do want to do more video/audio encoding in the near future. I have also considered using this as a HTPC in the future, so gaming on my big-screen (51" RP CRT, HDMI input) is also possible.
