The price ranges have been picked so Intel processors would have come as best price/performance chips. If i am curious to see the best p/p ratio for, say $100-150 or 160-220$ intervals, i can find other processor better worth to buy, with more AMD processors among them. The message of this article is loud: Buy Intel, not the best bang for your bucks! Just my 2 cents worth opinion
Ok, let's examine that. Really the only CPUs not on this list right now are the low Athlons and FX 8320, so that must be what you're sore about. Now yes, the 750K and 760K deserve mention at the low budget end simply because you still get four threads whereas the G3258 is limited to two ( and there is some suspicion that leads to stuttering. )
Compared to the i3, the 8320 gets you four more threads and an unlocked chip for $30 more. But those extra threads don't help much in most gaming right now or the immediate future. And in order to OC the 8320, you need to spend more on the mboard and cooling compared to the i3. At that point, you're not really building a lower budget gaming PC anymore, so the i3 comparison starts to be inapplicable.
Next, the 6300. Sure, going for the 8300 gives you two more threads, but again those aren't going to make any difference in a gaming first machine when you've already got six. The 6300 is already unlocked and the price difference between the two chips would pay for the CPU cooling you'd need to use it. So again, why pay more for the 8320 over the 6300?
Stepping up to your $160 - $220 range, The 8320 starts going against the i5. Again keep in mind the extra price in OC components to crank up the FX chip eats away at the price difference between the 8320 and a 4440 in a relatively cheap H87/97 board with stock cooling. In the vast majority of games you won't see a difference. In the heavier threaded games you may see some benefit in the 8320, but mostly you'll just have more noise and heat due to the OC. So again, a locked i5 is generally preferable. If you're in the budget for an unlocked i5, there's very little reason to consider an 8320.
Consider an 8320 like a cheaper Xeon 1230. They make sense to people that game but also spend considerable time on other CPU intensive tasks. As such, they aren't main recommendations in an article that is talking about best
gaming performance for your money.
