Which motherboard can handle with my RAM?

[xs7v3n]

Hi everyone, I'm new here at Tom's Hardware!
and also still new on building specific/proper and right components for my computer.

This are the things that i've gathered online:
AMD Phenom II X6 1090T BE
XFX RADEON HD 6870 BE ( I'm planning to crossfirex with the same graphics card someday)
Cooler Master Hyper 212+
Seagate Barracuda 7200 1 TB 7200RPM
Thermaltake Black Widow W0319RU 850W ATX
G.SKILL Ripjaws Series 8GB (2 x 4GB) 1600

this is how i am taking my time to find more information about the right motherboard i'm going to get with the following parts above and this is how i came to this choices:

MSI NF750-G55:

Foxconn A9DA-S

MSI 890fxa-gd65

ASUS M4A79T

This one is open box, am i still gonna get better benefits than the
motherboards above?

What motherboard can handle the memory that i got and is there any chance i can still add 2 x 4gb memory at 1600 [default]?

FMI: If you're going to suggest a motherboard, the one that has atleast two 2.0x16 PCI Express would I more likely choose better than the mobos with with x8x8 dual or 16x4x.

Thank you guys for your time, and please don't hesitate to give your own opinion and suggestions!

Why pci x16x2 and not x8x8? you're planning to use the current graphics card you have, being an AMD it hardly suffers if it suffers at all from x8 x8.

Unless you're specifically going to dump that videocard and keep the system and move to nvidia in the future, there's no real reason to aim for the x16 2x over the x8 x8.

As for the ram compatibility: you can download the PDFs from the motherboard manufacturer's website and/or it should be listed on their sites the list of "compatible" ram. Nowadays, though, mobo manufacturers have gotten very flexible in that respect and generally speaking so long as it's the right DIMM it should work. The most you'll have to do is change the timings yourself.

If i'm not mistaken, the IMC on the CPU is limiting the ram to ddr1333 unless it's overclocked. If that is right and I'm not mistaken then just OC the puppy... Hell, ^^ is a good board and that's good ram and the CPU/PSU can handle it. Why the hell not?
