Gaming graphics card for Optiplex 755?

[Colonel_1]

Hi, I have a dell Optiplex 755 tower and I wanted to know what graphics card I should get for running games like battlefield 4. I have a Intel core 2 quad q6600 2.4ghz with 4gb of ram. I really have no idea, so can someone help please?

A 750 ti that doesn't require a 6 pin connector would be perfect

I'm assuming you have the version of case that is wide right? Because some are really thin and can't fit a graphics card
