In terms of CPU's, AMD vs Intel CPU's are very different beasts.

The FX-8350 for example at stock + turbo (4.2ghz on one core) scores ~1.1 on Cinebench 11.5 singlethreaded, whereas the i5 at stock + 1 core turbo (3.9ghz on 1 core) scores ~1.7, but has more overclocking headroom (you can pretty much match fx frequency even with haswell without using exotic cooling)

However, FX 8350 has twice as many integer cores and is lower priced, more available. The 6300 is quite good if you want an unlocked cpu with many cores at a low price point.

Comparing the i5 4670k against an 8350 though - at a high overclock - represented by lets say 4.7 on 4670k (as i have on air), and 4.7ghz on fx8350 - with single core turbo to 5ghz cause it can

You have a ~53% lead on singlethreaded performance for the i5, and a very slight (~5%) lead on multithreaded (all cores loaded) for the fx8350.

i7 keeps the singlethreaded performance, but pushes multithreaded quite far ahead (~15-25%)

In terms of practical use, if you're heavily loading 6+ cores, i5 vs fx won't really matter - if you are loading 4 or fewer cores and you care about performance, you took the budget option with CPU and it really shows.

Sc2 and Planetside 2 for example make this extremely, painfully obvious, where overclocked haswell gives lower FPS than some people want in bad cases (i've seen sub-20 in an actual 1v1 ladder game, though it involved 2 maxed armies, aoe and a whole bunch of turrets with physics on) and that's while having a performance advantage over piledriver FX that ranges from 50% faster to as much as more than twice as fast



^This is what happens when you hit the sc2 engine really hard. The performance differences exist throughout the game, because sc2 is almost never graphically bound at any time FPS is at all low. Planetside 2 shows similar, dipping into the 40's and 30's on overclocked haswell (i didnt see worse, nor did i play it for long because it's an awfully coded, buggy game)

In the end the CPU you buy is decided by what games you are playing and/or what you are doing, how much of a low budget the build is, and how much of an opportunity the singlethreaded weakness of FX would have to be exposed, or stay hidden (if you ride the strong side of the cpu's with software that will use all cores)

So the money question is: How multithreaded is Rome Total War 2 and what else are you doing with the CPU?

The 4670k and Gigabyte Z87X-D3H, can get the CPU for $230 by pricematching with NCIX at ME and the mobo for $128 by pricematching NCIX at ME. If you rather stick with NCIX then CPU is $238 and mobo is $135.

I have an A6-3670K and play EVE Online fine, Dota 2 on minimums and Planetside 2 barely
