The most important consideration in a quad core is the speed of your memory. The second most important consideration in a quad core is the speed of your memory.

For a dual core machine, memory speed may still be important as I'm not convinced that DDR3-1600 can keep up with two Haswell cores.

If money is no object the new quad-channel Ivy should outperform a dual channel Haswell.

I see. Right now, I'm trying to swallow my cheapskate mind...

Do you think this and this would work "reasonably" or will it still bottleneck a lot?
(4GB is enough for what I do)

EDIT: Just saw the quad channel thing, hmm..

For an extra $40, you'll be able to run all four cores nicely.

Just do yourself the favour, lol.

EDIT: Also just noticed your mention of dual and quad channel. I caught "core", not "channel". Hmmmm

I agree that $40 to get DDR3-2400 memory vs DDR3-1600 memory is money well spent. However, you'll need to research carefully which CPUs and which motherboards will allow you to run the memory at DDR3-2400.

I put a great deal of research into my i5-3570k system. I was dead set on an ASUS motherboard as soon as I saw their line-up and how well they explain the design of the board. They had a bunch of standards in their lineup of Z77 boards and every one of them managed to clock 2800MHz or higher on the RAM with an i7-3770k.

I'm going to assume a k-series CPU on Z87 will do roughly the same; all boards achieving well above 2400MHz. For ASUS boards, I don't think the motherboard is going to be an issue. Whether or not the CPU can take it, on the other hand...

To be honest, it might be worth spending the extra $40 regardless and seeing how far you can push the RAM.

Will AVX2 be bringing anything to the table or would that just stress an already maxxed memory system? At least until LGA2011 gets AVX2

Looks like these could be fun when they come out:

The new fused multiply add instruction (called FMA or FMA3 in this thread) does bring something to the table. It could bring a lot (10 - 20% or so) if the memory system wasn't nearly maxed out. In practice, it brings only a little (3% or so).

Would love to see an enthusiast Haswell-E with 128MB eDRAM and no iGPU, pure CPU cache

If you don't use the iGpu then it will be switched off and it may as well not exist. It will then be a pure CPU cache.
We could do with some desktop versions. Hopefully in the haswell refresh.

I finally decided to go with this, as I don't exactly have a huge money tree... Well, all I'm hoping for is decent performance compared to the
2.3 GHz Core2 Duo I had before.
