Absolutely it is NOT worth the upgrade. Most of the performance of core I5 comes from its 4 cores. The Return on Investment for a 7600K would be horrible.
PC components depreciate in value faster than automobiles. When you buy components you should plan to make them last for 4 years or more. To do otherwise is costly.
What limitation are you facing right now? That CPU / GPU combo should be really good for 1080P gaming.
I bought my
Core i5 - 6400 on sale last year for $156
someone wants to buy it for $150
and my
MSI B150M Mortar Arctic for $98 from the shop
someone wants to buy it for $80
is this a fair deal?
