tf2 is very dependent on single threaded performance, doesn't really matter how many cores you have as long as it's over 2. your phenom proc is pretty old so that's definitely what is bottlenecking your performance. you could put a titan in your machine and it probably wouldn't make that much of a difference
the drop in performance from the new card is probably related to how well it does d9 stuff as dave has stated, newer cards may possibly be worse in this regard as they optimize for d11.
