Its not that bad, a lot of things are going multithreaded, especially games.
In that an FX-8150 is faster than my Phenom II x6, and yes i am giving serious thought to getting myself an FX-8350

Would an AMD FX-4170 Bottleneck a 7950?

Where are these highly multi threaded games I keep hearing about?
I see BF3 and maybe 1 or two others. One of the latest AAA titles ; BL2 still sees Phenom II's knocking about the FX8150.

Can i have a link to that BL2 bench?
The 8350 *might* be faster than an x6 in gaming. I did some research comparing different cache sizes on previous AMD chip generations and found the addition of L3 cache gave about a 0-15% performance increase. Comparing Athlon II x4 to PII x4 will probably give a good indication of this.
It does however rest on the implementation. It's not a simple case of "oh lets just add some more cache" - you have to control how it's shared between cores and what data is duplicated in L2. It's no good having a massive L3 cache is you've got a high miss percentage, you could fill the cache and then none of the data gets used (extreme case of course).
Additionally the reason why multi-threading isn't the be all and end all is because of Amdahl's Argument, that is, there will always be a single thread which cannot be broken down that becomes the performance limitation. In practical terms this might be the main program thread that sends data off to the other threads. You can get a case where because of the low performance per core the main thread is becoming a bottleneck, preventing utilisation of the other cores. Theoretically you could program a modular, decentralised piece of software but that's very difficult in practice.

Find ones, I don't want to seem like I'm giving you a review to suit my post.
Either way, we're in the last leg of this month and Vishera launch seems like it's this month, we'll see what happens then.
Humbug, while I come across as negative towards AMD in desktop space, my opinion of them in the mobile market is much, much higher than Intel, please bear that in mind and don't think I'm suggesting Intel for the crack, it's more because I genuinely believe it's a better option, but like I said, in this thread, I think the best course of action is hold off.
I want AMD to get the APU contracts they deserve, I'm using a lowly C-50, but it opens up options for minor gaming in a netbook/tablet, imagine their current iterations? Pretty powerful stuff.
I want a Windows 8 AMD APU tablet.
