lol @ your sig newbbuilder11
I wouldn't go with a Pentium for battlefield. It is known to have major stuttering issues on many of the latest titles which can take advantage of multiple threads/cores. Some cases the stuttering is so bad that the game is unplayable. The gameplay videos you posted use an i7 with the 750ti.
At this price point an i3 or 860k would be best. As well, with future proofing as the H97/Z97 boards will be able to utilize 5th gen cores.
OP if you could fill out this form:

It would be easier to suggest a build.
