Also dual core or Quad? E8400/8500 to 3.6-3.8ghz vs Q6600 OC'd to 2.8-3.0.
I know the quad will lose in gaming, but will it really be that much of a difference? Should I wait to go quad later down the road?
Don't feel limited to the 1100 limit, just would like to not go too far above it...
Will also be checking slickdeals for things coming up for a couple weeks until I order.
No, the quad will not lose by a big difference, if at all. If you run things in the background, the quad might even give better fps. Even if you don't, the Q6600 is fast enough not to be a bottleneck. Your games will usually be as fast as the video card can deliver, regardless of E8400/Q6600/overclocking.
FSX is an exception - if you play that you want a quad and OCing.
You can get a Q6600 to 3.0 GHz or more with DDR2-800. I'd get 2x2GB DDR2-800.
