I have been reading online threads about which is better and its pretty conflicting at times. I mostly use my PC for gaming battlefield 4 for future gaming. So before i buy, i like to ask. Is i7 3770k going to give a better performance over i5 3570k? or i can use that 100$ to upgrade to a better GPU later?
The i5 is great for gaming. You don't really need an i7 unless you frequently use applications that use more than 4 cores. If you do heavy photo, audio, and video editing and rendering, you may want an i7.
