Do you think that this setup will allow me to evetnually run 5 man heriocs?? Or should I just spend £200-300 on upgrading?
I find that running instances are easier on my computer than doing anything outside an instance. So, from my minimal experience on this subject....I would say if you can run 5 wow's outside of an instance...you can do it inside as well.

I am guessing that instances run better because of the lack of outside objects(other players, mobs, terrain distance).
