Just as the title describes. Its one or the other. All I do on my PC is gaming. Here is my current build: http://pcpartpicker.com/p/hqGnwP. Please tell me which choice, and why. Thanks!
My vote, 270X. Your i3 is not bottle-necking anything and will not bottleneck another 270X. If you got the i5, you would be heavily bottlenecked by the single 270X
