SystemBuild, Before I pull out my credit card...

I'm back! And thanks for those who have posted here or on my other topics. I have compiled a list of questions based off the replies I recieved. Some of you may have mentioned these in your comments but I turned them into questions. So you may read your own replies in 3rd person in question form lol


I'm at work and I'll be busy for the next 3 days so I won't be able to do much research on these things untill later, this is why I'm asking what appears to be silly simple questions, but I appreciate your help anyway if you're bored. Just answer what you already know, and if you research something FOR me then I will definitely be greatful for that. Don't break your back of answering me, as long as the answers are accurate. I'm sure there's a few bored people around here

QUESTIONS FOR RAM
1) As you know, I am trying to max out 64GB of RAM - There is only eight RAM slots available on the Dark mobo, so Is there any motherboards with more than eight RAM slots available? If not, will buying 8x8GB RAM modules be a good idea or will that affect performance or better it?
2) Regrading 64GB of RAM at the highest speed I can get, I heard this will limit my CPU's overclocking potential, is this true with the setup I'm currently deciding on? Does this limit exist even with the best motherboards money can buy? I'm afraid of having this much RAM now with possibility of limiting my OC potential. If this does happen, how much OC potential am I really hindering? Is it SO great that it should make me think about dropping my RAM? I prefer to keep 64GB.
3) Someone told me that larger RAM doesn't apply to my platform because the Dark mobo only has 1 Quad channel Bank, not 2, what does this mean? Nobody else has mentioned this before.

QUESTIONS FOR MOTHERBOARD
1) Which motherboards give at least 42 lanes for PCI-E traffic? I need 2x16 for graphics, 1x1 for sound card, 1x8 for RAID controller. Any cards installed other than two Titans will drop me to x8/x8 throughput and I want to avoid that. I need more than 32 lanes for PCI-E traffic. [1x16, 2x16, 3x8, 4x8]
2) Some have recommended the RIVE Black Edition motherboard over the eVGA Dark instead, others say the Gigabyte UD9. Which of these motherboards currently are the the best money can buy? If any, what benefits does the winner clearly have? How many lanes of PCI-E traffic does the RIVE Black Edition have, what about the Gigabyte UD9? True, most games barely even utilize more than 4 cores, soon 8, but think of this in benchmarking terms and future use. - So the real question is: eVGA Dark vs Gigabyte UD9 vs RIVE Black Edition vs ASUS RoG series vs MSI HighEnd-only boards, vs etc.. Is there anything else that could compete or beat these? If not, which of these are the cream of the crop? I was recommended the Gigabyte G1 Assassin2 as well.

I hear that people are moving away from EVGA due to BIOS issues, especially in the X79 chipset for them. So, because of that, forget the records broke by the EVGA Dark

QUESTIONS FOR SOUND
1) I was told that if I want the best of sound that I should ditch the Creative sound card and get myself a USB DAC instead. Something like the PeachTree Audio Nova, or the PS AUdio NPW. I guess these truly are that much better than any sound card on he market eh?

QUESTIONS FOR SSD RAID, CONTROLLERS
1) As far as my SSD's go in RAID0, the last time I heard that was a bad idea to stick SSD's in RAID0, but that was 2 years ago. Has this idea changed? What bout TRIM support? Lifespan of SSD's when put in RAID0? Is the idea of putting SSD's in RAID0 so bad that I should totally not do it? Or is there easy ways around the "wrongness" of doing this?
2) Someone said "Instead of getting two SSD's and running RAID, just buy one of THESE. This appears to be internal RAID. Why do this? How would this perform against 2x 512GB Samsung 840 PRO's in RAID0 without a card? Are these internal RAID setups truly that much more efficient? If so, how much?
3) I was told, very stricly, DO NOT MESS WITH DEDICATED RAID CONTROLLERS, THEY WILL RUIN YOUR LIFE, YOU ARE ASKING FOR GRIEF ON SO MANY LEVELS. Because of this statement I will avoid the troubles ahead of time and perhaps go without a RAID controller, which might change the answers in some of my other questions. However, DOES THIS including setting up an INTERNAL RAID on my PC? Something like the link shown here --> http://www.newegg.com/Product/Produc...82E16820785002.

QUESTIONS FOR VIDEO CARDS
1) Is the performance of 4 Titans so great that I should ditch the sound card and RAID controller, or is the performance increase not that significant? What is the difference of performance between 2 Titans and 4 Titans? Think of this in pure benchmarking terms.
2) If I plan on getting a new 4K TV, then I'm sure I'll need 6GB of VRAM, I wonder if the Titan Ultra or x290's will have enough VRAM? In that case I'll need at least dual video cards for maximum performance anyway, correct?
3) Waterblocks! I know there's several types of waterblocks for EVGA graphics cards, but what do you think about Koolance? They've been around for years and I'm sure they have good quality, but again, do they beat the competition? or is this a case where waterblocks don't make much of a difference who you get them from?

ALL OTHER QUESTIONS
1) What is the "Cylinder-shaped MacPro" due for release soon? I don't like Macs at all, but I heard it's comparable with whatever high end PC I am building. What are the cons? the pros of this MacPro?
2) I was recommended the MountainMod cases because of the size of watercooling I may need and the motherboard is something I even want to put watercooling on. Does this honestly look like the best route to go for a system like this? or do you know a better idea? http://www.mountainmods.com/. I was also recommended the Corsair 900D case. How does this stack up compared to the MountainMod cases?
