After work, I installed a new graphics card in my desktop - a Radeon 7750. It's taken my Windows Experience scores from 6.6 to 7.4, and I can now run Warcraft on "Ultra" graphics - with a few tweaks, I can now run at >60fps, rather than the ~35fps I was getting on "Fine" with the distance turned all the way up.
I then put all the old cards in their correct boxes - I have a tendency to put the old card in the new box, so the 5750 went into the 4650 box, and the 7750 box is left empty. I might end up putting one of the faster cards into the HTPC, but the card in there right now is pretty quiet.
