You state you want top of the line, but imho there are different levels of top of the line lol. So I will just ask, budget?
I can't say anything about the ASUS mobo you reference, but I think MaxPC went with the LGA 2011 socket and Sandy-E CPU because what else can it do? If it has to go a notch above a Core i5 CPU there is nowhere else to go but Sandy-E in terms of performance and price. But mainly price, as gaming performance is not significant between the two chips.http://www.anandtech.com/bench/Product/552?vs=288
Anandtech doesn't have a Core i5-3570K in their bench, so I compared the 3930K to a 2500K (which is about 10% slower than a 3570K). Yes, the 3930K looks great in most benches vs the 2500K, but the gaming benches near the bottom are relevant here, right? If $ is not an object, then yes, Sandy-E is the way to go right now. That may change though next year when Haswell comes out or when/if Intel releases Ivy-E.
The decent enthusiast gaming build includes:
- Core i5-3570K CPU
- Z77 / 1155 mobo
- 8 GB 1600 RAM
From there, each dollar gets only incrementally better performance. If you need/want the performance, yeah of course it's justifiable and worth it. I'm just saying
