Yeah here's another of these. But my question may be a bit more specific.

I do not plan on upgrading until skylake and I intend on overclocking for better gaming (Not just for the fun of OCing) to around 4.5.

I'm building the system from ground up for 1440p gaming and it's got an msi lightning 780 (in case that matters)

Which cpu is more suited for my needs (Mderate OC and heavy gaming) ?

As kristian said, there's no real difference between the two other than the 4670k is newer. I've heard that these newer haswell chips have higher heat production and lower overclocking headroom than the previous ivy bridge chips.

In addition, factor in the cost of the motherboard. I'd go with the one that I can find a good quality motherboard for the cheapest, which seems most likely to be the Ivy Bridge 3570k.

That link doesn't seem to cover OC performance, unless I'm mistaken.

Oh so no difference on stock and better OC on 3570. So unless I plan on upgrading when broadwell or refresh gets here, 3570 sounds like the way to go.

I dont see much use for 1150 outside of it not being dead. But since I won't be upgrading until skylake dead chipset with better performance seems more reasonable. Also your link was very helpful, 3670 is looking better and betterER.

I don't actually have the mobo yet. The gpu, psu, case and ram sticks are the only things delivered.

Is it untrue about fx? It'd save me another $50 or so which could eventually go into SLI 780s. I don't wanna do fx if it has unstable temps or just isn't as good though.

i5 k series: Great for everything, amazing at gaming, runs cool with low power consumption, overclocks well

AMD FX (piledriver): Great for multithreaded apps (video editing, 3d modelling), good for gaming especially newer titles that utilise more cores (worse on older titles that are single threaded), overclocks well, may run hotter, uses more power (3570k 77W tdp, FX 8350 125W tdp), BUT all on a budget (Can be 2/3 or 3/5 of the price of the intel products). The FX 8320 for example is £120~ and can be clocked up to FX 8350 speeds, saving £30~ pounds, which is £50~ cheaper than an intel i5 k series. AMD motherboards tend to have a lot of features for less money also.

All in all, if you're going for high end gaming, go with the i5 k series (3570/4670). If you want to do that on a budget, extremely well for the price, go for AMD. i5 wins in gaming, AMD can win for work apps like video editing etc, but AMD has recently come close to the i5's for gaming performance with the introduction of more core/thread support in newer games.

Well considering I already have an MSI lightning 780 I'd say I'm pretty much set on high end gaming. But having now looked at the 8320 it would save me upwards of $100 on a mobo/cpu solution.

Do you have experience overclocking that fx and is it on par with 8350 overclocked?

Haven't OC'd mine yet as amazon messed up my delivery of an aftermarket cooler. From what I've read you can achieve 4.7 Ghz relatively comfortably on the 8320 and 4.8 Ghz on the 8350 on air cooling alone. If you were to go with liquid cooling you could go even higher. Remember, this would be on the 990FX boards not the 970 boards due to the VRM's on the 970's. On the 970's you could achieve 4.4 comfortably.

Honestly, for you I'd say go with the i5. A single 780 will destroy current games anyway. From what I've read the higher end FX's (8320/8350) won't bottleneck any gfx cards except for potentially CF or SLI (don't quote me on that, bad memory lol). Future games may/may not have 8 core optimisation and consequently may/may not perform better on AMD systems; it's hard to speculate so go for what you need right now rather than worrying about the future. For a high-end gaming system, I'd say intel, but if you're still concerned about the budget then go for the FX 8320/8350 with one of the 990FX boards and an aftermarket CPU cooler.
