I'm thinking about building a new system (my first build, yay). I'm torn between Q6600 or Q9300. I'll use this mostly for gaming and doing 3D CAD (and of course internet and e-mails). I don't know how much difference of the two are. I prefer something that last longer (since I don't plan on changing for 3 or so years). and I don't think I can afford anything higher than using Q9300. So, any comment? the other parts are listed below

Nice looking setup.

I'd certainly go for the Q9300 out of those 2. It performs a little better, but it also supports SSE 4.1 which the Q6600 does not. Not much uses that instruction set now, but you'd be kicking yourself if a new prog. comes out that uses it and you only have a Q6600.

Some guy (here) said this:

Compared to the Q6600, it's about 7% faster. Unfortunately, the 7.5x multiplier limits its overclocking potential, and 3.5GHz is about as far as you can go before hitting a FSB wall.

The low multiplier aside, it's not a bad CPU, considering it's the same price as a Q6600. It doesn't blow the Q6600 away, but it is slightly faster and lower power consumption is always welcome.

Here's a direct comparison for you: http://www.xbitlabs.com/articles/cpu/display/core2quad-q9300_4.html#sect0

Another review said this (here):

the Q9300 is easily an improvement over the Core 2 Quad Q6600 on all fronts.

With GPU, a GTX260 (216 version preferably) would cost you a bit more, but the extra on-card RAM (896 vs 512) would be nice if you want to use a large resolution monitor for your CAD. Just a thought; the 9800 GTX+ really is a great card.
