Budget is $200.00, but don't really want to spend that much.

Choices:
Intel Core 2 Duo E7200 ($139.99) or Intel Core 2 Quad Q6600 (199.99).  I have 4GB of RAM, ASUS P5N-E SLI, and EVGA GeForce 9800 GTX KO.  I am wanting to upgrade my current CPU which is a 3.2GHz Pentium 4 HT so I can take full advantage of what my system will do.  I just cannot decide which CPU I want.

You may also want to consider the E8400 3.0Ghz C2D.

A nice CPU for the money. All three are nice though, just comes down to how much you want to spend.

 

it is hard to choose. it depends on what the purpose of the rig. if you are a hard core gamer or ocer, it is better to go with E8400 and if you do a tons of multi tasking,   Q6600 is a good choice.  E7200 is a great bang for the buck and E8200 is not bad so.

if i were you, ill go with Q6600.  

 

i have a Q6600 and would HIGHLY recommend it, its amazing!

The Q6600 all the way. No chance of it bottlenecking any other parts of the system, and you'll never run of the cycles.

This question has been nagging at me a little bit as well.  I've been looking at the E8200 and its Quad core clockspeed equivalent.  I'm trying to figure out for primarily gaming (although I do other things) purposes, if the quad core is worth the extra cash, or if I should actually considering swinging a lower clockspeed quad core like a 2.5

Q66 alll the way ^^
