Best upgrade for my system?

[heyaz]

The operating system pare it down to bare min I bet there a ton of services that yeh can get rid of, that'll help

Have done every software/OS tweak I could find. Turned off every service I could find, run no unnecessary background processes during play, indexing is completely disabled, paging is disabled, all vista effects are disabled at the service level. Ton of registry tweaks as well.

What resolution do you play at? the higher the res the more cpu it'll take, wow does allot of the graphics on the cpu. Adding a new grpahics card will do next to nothing.

800x600, looks terrible

I'm curious if your statement about a new gfx card doing nothing is true. The one I have is pretty bad, and people with my same CPU and better gfx cards seem to be getting much better performance.

Do you have max background frames set ?

13 in background, 45 in foreground

affinity set?

Yes, but I've noticed very little difference with different combinations. Finally just gave the foreground 1 extra core.

what kind of addons are you running?

Bare minimum. Gladius, jamba, and a cooldown timer. No UIs, no quest helper, nothing I don't absolutely need.
