X-plane is like 150GB installed. Start there. When you need to dedicate an entire SSD for a game, you have a problem or a work of art.

Right now we're lucky we have 4 channels on X99 because Intel long ago made the move to have more than dual channel memory controllers on their enthusiast platforms. The interesting question will be whether or not Skylake is more than dual channel, but I'd probably bet against that... although I would be curious to see what AMD is going to do, as offering more memory bandwidth could be a way to counter Intel trying to use brute force with their process node advantage by offering up advantages like 128MB of L4 eDRAM cache on chip to make up for lower desktop memory bandwidth.
also, while X99 very well might support these registered/ECC modules, I wouldn't count on consumer DDR4 to scale much past 16GB anytime soon. I read somewhere that Skylake will support up to 64GB of RAM, and if we infer 2 channels, that means we'll probably see 32GB sticks of DDR4 in the consumer space at some point, which would mean 128GB as a more realistic upper end on X99
it might not make much difference on the CPU side of things, but APUs are starved for bandwidth and would really benefit from increases there
most desktop users who use a dGPU will care more about the significant increase in module capacity, but with the cost of losing double slots per channel, that advantage will take a while to be seen.
I would honestly be surprised if ASUS fails to release some RoG board with TWICE THE RAM. DOMINATE THE COMPETITION. ROG. #YOLO. Yeah, honestly I would want one just to play with. There's no way I could afford, much less justify, the purchase, but that much RAM is just ridiculous.
Skylake? Dunno. Broadwell? Isn't that still DDR3? It's supposed to be LGA 1150, right? But every single modern platform I've seen - LGA 115# and AM#(+), and then some older Intel sockets (Core2, first gen Core i) - is dual channel with up to four slots. L4 cache seems almost like system memory rather than a cache as we now know it. 128MB of a-few-hundred-clock-cycles-worth-of-latency memory is massive. (And AMD still can't get their L3 to work right, which I find somewhat amusing)
"Soon"? Yeah, agreed. We're still stuck on 8GB DDR3 for consumers and enterprise is just now getting 16GB DIMMs. We'll probably have 32GB modules out somewhat soon, but I bet it takes a couple years. 64GB might happen towards the end of its life.
Yup. I'm waiting for information about Carrizo before I get another laptop. If it's a good upgrade over Kaveri (GCN 2.0 and 1024 shaders, please) and supports DDR4, I'll definitely consider it for an SFF briefcase build. The alternative is Haswell or Broadwell and a Maxwell GPU. I'm looking forward to DDR4. It sounds stupid to want RAM to get better, but APUs and SoCs are the future and they're starved for bandwidth.

Right? Now, if it were ReRAM... Suddenly, that awesome ULLtraDIMM (SSD in a RAM slot, look it up) seems a lot less awesome because the latency is still an order of magnitude or two higher than RAM. 128GiB DIMMs? I mean, we all knew it was inevitable, but still!
