Hello together,
I'm new to the forum!
I just had a quick question, I'm building a new pc
and I'm planning on using the following components
Mainboard: "Asus Rampage iv Extreme"
CPU: "Intel Core i7-4930K Ivy Bridge-E"
Originally I was going for the "Intel i7 4960X ivy Bridge", but I don't think the difference in benchmark result
are that great, that I need spend almost twice as much for it.
My question is just about the L3 cache (12MB on 4930K vs 15MB on 4960X), does those 3MB make that much
of a difference, that it is worth spending the extra $500?
RAM: I saw that both CPUs only supports DDR3-1333/1600/1866, therefore my question if it makes a difference if I buy memory
that is DDR3 2400, or if that is basically just a waste of money, because the FSB of my memory is higher than what my
CPU can provide?


My questions summary is:
1) L3 cache importance (12MB on 4930K vs 15MB on 4960X), do those 3MB make that much
of a difference performance wise, that it is worth spending the extra $500?
2) Both CPUs only supports DDR3-1333/1600/1866, therefore my question if it makes a difference if I buy memory
that is DDR3 2400, or if that is basically just a waste of money, because the FSB of my memory is higher than what my
CPU can provide?


Thank you for helping me in this matter :-)
As I'm excited to get my parts on order and start throwing it together.....

As you can see in the benchmarks the cache doesn't make that much difference to performance.

It is the mobo that determines the ram speed. Look at the mobo website for speeds supported.

High speed ram helps with video editing but not much else. If your only gaming, then you'd be better to go with LGA1150 cpus and mobos with 8gb ram. The X79/LGA2011 is worth the extra money for video editing or real high end gaming machines etc - because you can get 6 core cpus and more pcie lanes eg for quad sli.

1. you only want the 4960x for bragging rights. the 3mb cache and couple hundred mhz is simply irrelevant and certainly not worth 500$. if you want the best of the best though and you can afford it then the 4960x is the cpu for you.

2. you can buy as fast ram as you want/afford, the 2400mhz ram will downclock itself to 1866 and better timings compared to standard 1866 so it's not a waste. remember you need 4 identical modules or a 4 channel kit for the x79 platform.
