Your CPU is more powerful than the ones in the PS4 and the Xbone, you have the same amount of RAM and your GPU is the AMD equivalent of the PS4 which is slightly faster than the Xbone. Overall from a PC specification perspective, your PC is more powerful, but it must be noted that developers will end up optimizing games a lot better for those systems than for PC, so your graphical settings in games mightn't be as good.
