You are comparing Apples and Oranges. Video game consoles are closed systems and games are optimized to their exact hardware. Game developers and programers can focus on using the exact parameters of the system, and don't have to worry about whether the end-user has a GTX 650 graphics card, or a $1000 Titan, or a weak CPU or a i7 4930k.
You just really can't directly compare either a XBOX One or a PS4 to any desktop PC and have an exact comparison.
But to give you "sort of" a ballpark comparison The i7 3770 is WAY more powerful than the processors in either of the new consoles. I mean compared to the AMD APU processor in the PS4, the i7 3770 is like three or four times faster/more powerful. It's not even close. Seriously.
And the graphics card comparison gets even murkier. About the closest you can come comparing a discrete graphics card to the PS4 would be a Radeon HD 7790 or in that area, or yes maybe even the R7 260x.
But again, the fact that console games are coded exactly to the console's system specs (because they are always the same) allow developers to really make games shine and look great on them with fairly modest (by PC standards) components. And in a year or two they'll really start to figure the new hardware and games will really start to look fantastic.
The advantage to PC's is that they can always be upgraded. The i7 3770 is still a very good processor, and will be for at least another year or two. But the R7 260x is not that great of a graphics card. Middle range. But if you wanted to and had the money, you could build or buy a system that is so far above a PS4 it would be ridiculous. Stupid ridiculous. This is what makes PC gaming so great.
