First, let me ask you this, what resolution and what kind of activities are you going to use this computer for? If you just want high-end gaming and Youtubing, but are not going to do heavy video editing at higher resolutions, than I don't recommend going with a Haswell E build. Haswell E comes strait from the server industry, and is complete overkill for "Video Commentary". If you simply want to spent a ton of money to show off, than here is a build I recommend.
Oops, forgot the monitor. Here is some modifications I made (Sorry to break this to you, but getting a 1440P monitor is the only way to make this build practical, and it puts it over budget). I HIGHLY recommend sticking with the 1050 socket, as DDR4 RAM and Mobo are still way to expensive to be practical or efficient-
Have one major issue with that build logainofhades. SLI 970s is made for 4k gaming, so just getting 2 1080P monitors squanders that capability.
I would disagree here, as programmers are becoming increasingly horrible at coding games. My gaming system just meets the minimum requirements for AC4. Watch dogs, on ultra @ 1080p could use such horsepower as well, due the horrible coding.
You cant deny, however, that most games arent Ubisoft. Games like Civ BE, Metro Redux, Farcry 4 (same engine as 3), and many others (not by Ubisoft) are well optimized. I will post benchmarks when I gain access to my PC.
