Q6600 on DS3L is a pretty sweet setup isn't? I love mine, it really delivers a lot of bang for the buck.
Pair it with a decent video card and really get a cheap "jack of all trades" to throw at gaming, rendering, video conversions, etc.
Hard to not feel satisfied with such a budget quad-core build. I bet a budget spider build probably feels equally satisfying provided overclocking is not important to the end user.
