Damn, how much did that set you back, is the performance of DDR4 even noticeable?
Too much? Really IMO the Motherboard was $100 dollars too much, and the DDR4 wasn't too bad actually, its about 80 dollars more than a high spec 16GB DDR3 kit. But I saved about 90 bucks on my CPU (Bought it in store at Microcenter, instead of online). I ate the extra cost for the Motherboard though, The ASUS boards have more Pins in their Sockets which supposedly allows for more efficient, stable, higher Overclocks for Haswell E, and since I wish to overclock I needed a board that had robust chipset cooling and features, so X99 Deluxe it was.
I can tell you that my synthetic benchmarks are far higher than they ever were with my FX 8350 and 16GB of DDR3 @ 1866, and in gaming? well its a bit faster, but not drastically so.
I'm basically betting that multi threading will become more and more prevalent in games coming down the pipe because of Mantle and DX12, and I wanted a powerfull CPU that will have long legs and an upgrade path. Broadwell E will be on X99 in 2016, so I will be able to upgrade at that time.
