hello, my rig is i3-4160 GTX 750 Ti 8 GB of RAM, i am thinking of upgrading my processor to an i5-4460 because ive read that 4 real cores are needed these days to play modern games, and ive also read that it makes my rig "future-proof" as well as more stable fps in games. Is this true? should i upgrade? or should i just upgrade my GPU to a better one that is almost priced the same as the i5-4460 (I can't upgrade both).
