Isn't the whole point of dishing out that kind of money on an 8 or 10 core chip is it's supposed to be the be all and end all, and cover all your bases?
Actually forget that for a second. My comment was very specific to his situation. Dude has a 5960X @ 4.7 which is faster than even a stock 6700K @ 4.4, so it'll churn through single threaded applications without breaking a sweat. And by virtue of its core count, multi-threaded performance is top notch as well. If he then "upgrades" to a 6950X @ 4.2 or 4.3, then he's actually regressing in single threaded performance. Ok yeah sure if the majority of his CPU time is spent with multi-threaded applications, then the 6950X might be worth it if he could get decent resale value on his 5960X.
