They will be more expensive and I doubt the performance will be that must better than Haswell, but if you plan to run multiple graphics cards and such it might be a good way to go as they have way more PCIe 3.0 lanes.
If you don't already have an ivy bridge then you buy the haswell. On the performance level its kinda meh and comparable to ivy. What you do buy haswell for is the motherboards and the power efficiency of the platform.
Quick question on OCing: I was watching the video that posted earlier about the "4-way Optimization" that comes on the new Asus Z87 RoG Mobos, and I was wondering if a Noctua NH-u12s would be good for pushing a 4670k to aroung 4.0 to 4.2 Ghz. Or would I need a Liquid CPU Cooler?
You won't have problems overclocking Haswell to 4.2, with a cooler similar to that Noctua.
I'm using the Phanteks 12DX on a 4770k, and it keeps my temps below 70, while I stress it with prime 95. Ideally, I would want my temps lower, but it won't get as hot during gaming sessions.
I used the one click overclock to 4.2, it's a really nice feature. Probably get a custom loop to put on the CPU, reduce the temps more, and boost the clock.
Dude, AIO liquid solutions aren't necessarily better than air coolers. You can achieve similar thermal performance of the H100i, with an air cooler for 3/4 of the price, like the 14PE.
That's fair enough. But, for an OC of 4.2, you only need a inexpensive cooler. I find the AIO units to be more expensive than their relative thermal performance.
An AIO cooler, and an air cooler, capable of the same performance, the AIO would be more expensive. If that makes sense?
I'd recommend the Xigmatek Dark Knight Night Hawk edition cooler. Costs $30, or there abouts. It'll allow you to overclock to 4.2. It's a nice unit. Preferable to something like a H60.
It's very appropriate for your needs, and Logan would recommend it. Good thermals, good acoustic performance. I think it looks good, too. And it is cheap. It'll get you to 4.2, comfortably.
