In need of advice: AMD Radeon HD 7750 vs NVIDIA GT520

[Riddles]

Hey, I'm deciding between buying to computers.

I need some help to find out which of these two cards is better for gaming. (I don't intend to play games on ultra/high settings). I just need to know which of the two, AMD Radeon HD 7750 or nVidia GT 520, is better for gaming. The games I intend to play are things like PayDay: The Heist, Call of Duty: World at War, Saints Row 3, Darksiders 2, ARMA 2.

If you'd like to which CPU and other things the computers have you can follow these links to get to them:

Thanks in advance for any advice.

1st one is best.hd 7750 is 300% better than gt 520. Why do you want that prepre built cpu.at that price you can assemble your pc with more powerful.

That's not even a competition. The HD7750 crushes the GT520 in any games you throw at them.
