Now... that I have had a cigarette.. I'll give.. a thoughtful answer to the post that was made earlier.
First link from Crowe...
Showing Phenom II 955 vs Core2Quad 9550
Price difference... 9550 $290.. This was the high end CPU at the time of its generation's release, as you may or may not know, Intel CPUs drop very little in price from their release date.

Discontinued.. Your link may be pretty to look at from a computer geek's historian standpoint, but its completely irrelevant to in regards to building a new system TODAY.
The Phenom II 955 is still available from newegg, but its actually 10 dollars higher than the 965, so further irrelevant.

Your second link showing Phenom II 980 up against an i5-3470.. This link is a bit more relevant. 980s are no longer available from newegg. The 965 again, is still available for $85. They are identical CPUs, the only difference is the stock multiplier settings, they even ship with the same cooler.. Once again.. priced at $85..
How much is the i5-3470? $199

Well hell, its over 2x as much. And funny, not one single bench in that link shows a 50% performance increase for over twice the money. I'm not saying the i5-3470 shouldn't be considered for the OPs build, but if you're seriously expecting an $85 CPU to perform on par with a $200, you really need to think about your logical processing.
Yes, I'm aware that when Phenom IIs were released they were priced higher than what they are today. But once again, while this may be relevant from a historian's perspective, it bears little relevance to building a system TODAY.

The third link, yup, the 8350 stock to stock outperforms the 980. Yes it costs more, yes, the performance difference is not that substantial. Thats about the only relevant information in your post.
