Pretty close. Our current setup is a 4790k @ 4.7ghz and 32gb of ram in a dallas, we will soon be moving to a 6700k @ 4.7ghz and 32gb ram in new york. It's not a huge upgrade, but hopefully it will give me the chance to rethink how I do some things. Our cpu is our main limiting hardware factor, it also happens to be one of the best performing ones for minecraft that money can buy. It's not cheap at all, but that is why we push donations. There's no amount of money that would magically up the render distance, and due to server crashing when we had it anything above 5, I don't think it will be going up until something changes. I would expect that mojang would be getting on the issue asap, but hey, they did take 289days, 17hours, 46minutes just to mark one of my bug reports with "done" and post this "_/=\o_" in the comments.
