[QUOTE=kladner;351299]More cache? More cores?[/QUOTE]

Umm...? the i7 has 2MB more cache I believe but same cores. That's why i7 is near useless on P95.

[QUOTE=simon389;351279]This actually feels in the ballpark of what I want. Would you edit it for my particular situation above?[/QUOTE]

Start with my components. Skip the OS, SSD, and case. Choose a different CPU cooler as your existing case probably can't handle the huge radiator and fans.

Then look for equivalent (or better) components that are on sale at newegg.

IMO, invest your money in:
a) a K series non-hyperthreaded CPU for overclocking
b) fast RAM, DDR3-2400 or better
c) an efficient power supply, the extra upfront cost should pay for itself in lower electric bills.

IMO, do not invest your money in:
a) motherboard - choose the cheapest board from a reputable maker
b) quantity of RAM
c) disk, case, etc.

What is the fastest K series haswell non-hyperthreaded CPU available?

Edit: nevermind, answered my own ?: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16819116899[/url]

Going with this RAM : Team Xtreem 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2666 (PC3 21300)
[url]http://www.newegg.com/Product/Product.aspx?Item=N82E16820313322[/url]
and this cooler: CORSAIR Hydro Series H100i Water Cooler
[url]http://www.newegg.com/Product/Product.aspx?Item=N82E16835181032[/url]

Otherwise the rest is:
Rosewill FORTRESS-450 450W PSU : [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16817182081[/url]
and
MSI Z87-G41 PC Mate LGA Mobo: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16813130695[/url]
CPU: Intel Core i5-4670K Haswell 3.4GHz LGA 1150: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16819116899[/url]

I will order this in 24 hours unless somebody gives me a good reason not to :)

Sorry, I made that mistake on my Haswell, the low end chipsets don't support memory OC=1600 MHz limit=waste of money on ram. I did a little checking on newegg and it seems only the high end Z87 has it... :no:

Correct.

However, these also break the bank in a big way.:smile:

Having put this out here, NOW I look more closely and see that these are all Sandy Bridge. :blush: Oops.

Thanks for the correction. Yes, the motherboard must have the chipset designed for Haswell.

So will this MSI board run the ram at 2666? Total will be $619 btw.

I don't know about MSI. I honestly haven't even looked at any motherboard not from ASUS since I first started looking into building a computer (for myself or for anyone else). I've seen a lot of videos from some guy named J.J. (you can see them on Newegg) who goes into a lot of detail. I'm satisfied, at any rate.

One of the things they said was that all their Z77 boards (including entry level) COULD run 2800 MHz even though official support was up to 2400 MHz. You DO need a high end processor, so you're best with the best i5 as far as that's concerned.

You could try this, instead. [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16813131981[/url]

A few more dollars but this board OFFICIALLY supports 3000 MHz. Holy F---.

Make sure you have room for the H100i. Also, when I got my H80i about 8 months ago the firmware was garbage. Yes. Firmware for a freaking pump. I'm sure it's better by now, but just be wary of this. I'll look into this a little later.

Those fans are a bit obnoxious without a controller. The controller that comes with the pump is controlled by software which could be equally garbage.

Try to get [URL="http://www.newegg.com/Product/Product.aspx?Item=N82E16820211803"]THIS[/URL] in your mouth.

BTW, almost all Z87 motherboards have 3000 MHz memory support.

EDIT: Z77 is not Haswell.

EDIT2: I have ordered 5 ASRock motherboards in the past, they have been quite good.

I am pretty certain a 4670K would be pretty much the same(at the same clock rate).

Would a larger cache help? Not sure. Will Prime95 take advantage of a larger L3 cache in any useful way? Prime95 is probably the person to answer that question(aside from benchmarks). I seem to remember him saying in the past that it isn't optimised for >512kb per core.

Prime95 is optimized for a 256KB L2 cache.

I do not have any benchmarks to support this conjecture: I do not think any larger L2 or L3 caches available today will help prime95.
