That is awesome, I do want to mess with that platform as well, I would love to get an Evga x58 ftw3.
as for the oc, I have never done one but I do want to learn and mess with that, both the cpu and gpu, the non k was just included with mobo but if my local shop gets a k I will snag it (he sells em for $20)
I absolutely love seeing people still using, pushing, and enjoying this older hardware today. For me it is far more interesting and fun to mess with than new stuff, my Ryzen system is great but I don’t love it, I don’t want to keep messing with it like I do with these.
