Xeerow :
Thanks for the responses everyone.

no , you will not regret buying i7-5960x , That is the strongest consumer oriented CPU ever , it will last really really long before you will notice
your system being "slow" or being "older" to new CPUs
on a side note : what will you use the 5960x in ?
I'm trying to build the most future-proof computer money can buy. So right now I have the MSI X99S Gaming 7 mobo and 2x 980 Ti's, and I naturally went with the most advanced LGA-2011-v3 CPU. I'm starting to rethink this decision though, I might go for the 5930k instead.
5960x has 8 cores for a 1000$ price
5930k has 6 cores for a 570$ price
TL;DR : 2 extra cores for 400$ more is honestly too much , If extra 400$ is worth nothing for you then get the 5960x
on gaming performance is the same between 5960/5930 as they both have more than enough hyperthreaded cores
on computer performance 5960 might get you more performance in rare situations where as much cores are required
which translates to maybe 1-3 seconds better render time or 1-2 more fps in games ,
Newer games are going to use 6+ threads , while 5930 has 12 thread so you will have much much time till games even start to use your CPU full power .
Do not forget to get at least a 2011-v3 cooler that is rated for 140+ watt TDP
