Sabertooth X79 or Asus Rampage IV for my build

[Dhammel1]

I am reaching the absolute MAX i can spend on my rig, I have basically come down to the last element, the Motherboard..... I am caught between getting the x79 Sabertooth for $306.97 or the tried and true Rampage IV for $409.99. I KNOW the Rampage is the better of the two but is it neccesairy for my build... i will be overclocking the CPU.

These are the two cards

I AM ALSO CONSIDERING the x79 Extreme but iv seen bad reviews for it on Amazon/Newegg.

Platinum rated supply is probably a little overkill. Gold is plenty.

SeaSonic X-1050 about $50 less.

Sabretooth only really supports 2 way SLI it seems. But I doubt you'll need more then dual 780s, or dual 800 series when they come out.

Rampage gets you a PLX chip and Quad SLI if you want to do it.

Not a huge fan of the new 'gold standard' asus boards, doesn't match the DCUII video cards, so I avoid them on principle, doesn't matter since you went with EVGA, would still match better with the Sabretooth, but that is aesthetics only.

Rampage IV I think it is... now how about the new "Black" edition, is that necessary?
I know its a few days off but i could wait if i needed to, already considering the 780ti so i might be waiting a few more weeks as it is....
Given that i WONT be buying 800 series GPUs the biggest upgrade id be doing is a third or fourth 780 so i guess that gives me that overhead... if i do the Rampage.

Does it have enough PCI Lanes for me to really do the Sabertooth in SLI. I understand motherboards as much as a 10th grader so i apologize for all the questions?

PCIe 3.0 at 8x is more then enough for any modern video card. Which is how they get you Quad SLI. The PLX chip is a bridge that allows for even more lanes of traffic, but doesn't increase bandwidth. It will introduce latencies into the system when you use less then 3 cards, but with 3 cards or more will perform better then a system without one.

Chip itself can provide 40 PCIe lanes, usually they reserve about 8 for internal stuff (SATA controllers, NIC, USB)

X79 will get you 16x/0x/16/0x, or 16x/8x/8x for triple SLI.
X79 + PLX will get you 8x/8x/8x/8x/8x usually.

So dual cards will have maximum throughput, though they don't really need it. Only your first card in a Tri setup will have full speed, the other two will run at 8x, again still fine.

PLX chip will let you plug in an impressive array of cards, but will slow things down a bit with a single card or dual cards as all traffic will go through the SLI bridge regardless.

Sounds like the RIVE is what i want... I just dont want to shell out the extra $100 sounds like its better for the long term...OH WELL!

I just wanna say thank you for your help everyone on here has been very informative
