When you take into account that Intel offers no upgrade path socket wise there's no way you'll be able to upgrade that motherboard with a new CPU after 2-3 years anyway. So the only logical solution is to get a power performer now that will last as long as possible.
Actually I'm 100% right....
A power supply that doesnt have the correct distribution wont support future upgrades. The right one will be good beyond this one build..
Regardless of the "Future" everything currently available or near release is socket 775. He'll have plenty of time to pick up a quad CPU if/when he wants.
As I stated I dont disagree with the statements, except in the context of Toads questions/remarks. He wont go "wrong" either way. He certainly can do everything he wants to with the lesser CPU right now (based on his comments). If/when he wants to upgrade he can pick up a better CPU...probably for less total (for both) then the quad costs now. That doesnt make getting a quad cpu now the wrong move either. I built out a 6600 on a P5K-e MB when the P-35CS was just coming out. Basically exactly what your recommending now except the quads are the new best thing. It's good for years still but I'll grab a quad when they go "closeout" in another year or so...
Toad can get 85%+ of the performance of a 6600 and still grab a quad later. It's not a right or wrong choice if he has a clear understanding of his needs and the tradeoffs. His question was if he will see a big difference in performance with the 1st build vs the 2nd and my answer is still no..
However he should get a top notch PS not a 400W job. He needs to get some flavor of P-35 MB and should get a 3850/70 or 8800GT or drop back to a "budget" VC...the 8600 is a waste...
In the current world the CPU isnt the bottleneck in a dual core system for normal use. Currently PS is the biggest hurdle for most upgrades, very few systems even 2 yrs old have enough 12V rails and/or amps per rail. VC's are the 2nd "Bottleneck". AH however doesnt need alot and gains little from a "killer" VC so a 2nd generation card is fine. If I take V-snyc of my 7900GT runs AH at over 200 fps most of the time.
If I was doing a current build I'd put in a quad as well, but thats not answering Toads question in the context he put it. He will see a minimal difference (~10-15%){and probably much less} between the quad and "entry" cpu in the tasks he outlined and his FR in AH probably will be Vsync capped either way (assuming same VC in either system).
