Quote - Also, is there an AMD quad?

The only quad-core system you would be able to get from AMD in any near future is the Quad-FX, although I would strongly advice against it.
It needs to have two processors installed, which means you have to double up on CPU-cooling and which also means that it can draw about 400 watts in idle-mode. It's quite the radiator.

Another thing, if you want to buy a QX6700, don't do it at Newegg, they overcharge.
