Honestly, the current generation of consoles (xbox1/ps4) is using lower end AMD 8 core processors (jaguars). What this means, is games will start to be made to optimize 8 cores ,and with mantle (supposedly), the 8 cores will be more utilized. I would honestly say go for the 8350/8320 and overclock the crap out of it. Unless something major happens in the next 2 years, those will hold you off for a long time. Take the money you save and apply it to a GPU and compare it.
edit: NOTE*, I am 100% aware, that stock vs stock, the intel smokes the amd.... Im simply saying, that kind of performance isn't required, and dollar for dollar, the AMD wins honestly.
