Memory: Speed vs Amount

Hello once again, I have a question that I came across when browsing for a new Motherboard.

I am building a new computer and I posted once, in order to get some help, which I did (thanks for that :)  )

I have been looking at some EVGA mainboards and I have come across 1 that sais it supports up to 16GB RAM up to 2600 MHz speed, and another board (slightly more expensive) which supports up to 24GB but up to 1600 MHz.

Is this an easy choice or there's more than that to it? I mean, it's an 8GB gap and a 1000 Mhz difference, what are the pros and cons of picking one over another?

Just in case, here they are:

EVGA X58 - http://www.evga.com/products/moreInfo.asp?pn=141-BL-E76...

EVGA P55 FTW - http://www.evga.com/products/moreInfo.asp?pn=132-LF-E65...

Thanks in advance!

Got to read the fine print the 141-BL-E760-A1 says 1600MHz+ {plus} ; I know it will support at least 2000 MHz or higher.

132-LF-E657-KR Tested RAM Corsair - http://www.corsair.com/configurator/product_results.asp...

It's all about the Memory Multiplier with either of those MOBOS.

Also, you need to know they are (2) two different architectural Intel boards - X58 1366 i79XX & Tri/Hex Channel (6 DIMM slots), and P55 1156 i78XX/i5/i3 and Dual/Quad Channel (4 DIMM slots).

Further, Windows 7 x64 needs 4GB to work 'well' - and 24GB is great if you make a living by editing countless image layers for Professional use or make a living editing HD Video with Adobe Premiere - or need to have every application on your entire HDD/SSD open at once. Gaming 4-6GB is plenty.

Then speed, 1600 MHz is 'ideally' fast enough to support OC'ing 4.2~4.4GHz, and the 1800~2000MHz will add maybe 2-4+ FPS to the GPU rendering.

and a price difference of $200. If you are going to SLI more than two cards, then go with the i7-based x58 Classified, if not, get the 1156-based board.

or if you will in the future add SLI/CF 2+ GPUs, then the X58, and still the X58 is a better choice if $90 won't break the bank {309-219 = $90}.

There is a bit more to it.

The X58 chipset supports 6 slots of ram populated with 4gb sticks for a total of 24gb. Note that you will need windows-7 pro since home premium maxes at 16gb. The X58 chipset also supports more high speed pcie x16 slots. That is useful if you will be using two or more very high powered graphics cards.

The P55 chipset is limited to 4 sticks of ram and 16gb. It also maxes out at two X8 pci-e slots.

The maximum ram speed supported is of interest only to record seeking overclockers. Real application performance and FPS(vs. synthetic benchmarks) is minimally impacted by ram speeds and timings on intel nehalem processors. The difference is on the order of 2-3%. Not a big issue.
