Unless you need an upgrade like *now* due to a hardware failure (been there, got that T-shirt, heh), I would recommend waiting, specifically for the new Pascal GPUs from Nvidia if nothing else. The Sandy Bridge chipset (which I still have and use in 2500K form) is showing its age though. If I were in your shoes, I'd wait until next year, maybe 4 months or so when the new stuff comes out?
