It looks like i5-6600k is on sale from 369.99 down to 249.99

I'm wondering if this is an upgrade WORTH to grab for my build:
Intel Core i3-3220 3.3GHz Dual-Core Processor
Asus P8B75-M LE Micro ATX LGA1155 Motherboard
Corsair XMS3 8GB (2 x 4GB) DDR3-1600 Memory
Gigabyte Radeon R9 290 4GB WINDFORCE Video Card
Corsair Builder 600W 80+ Bronze Certified ATX Power Supply


Edit:
i3-6100 is on sale too from 155 down to 119

Depends what you're doing. If all you're doing is gaming, any modern multi-core processor will be just fine. If you do rendering or anything that's actually processor intensive, then upgrade. Gaming is mostly graphics card intensive.
