so i have an i3-2370m dual core processor with 2.4ghz of clock speed and Intel HD 3000 sandy bridge.

im just wondering how much framerate would i get in increase if i upgraded my cpu to a quad core i7 with the same 2.4 ghz of clock speed. let's take black ops 2 as an example, i play on 15 fps on low setting on black ops 2, how much fps will i get in increase if i upgraded my cpu to a quad core at the same clock speed?
