Games Suggestions

So, I have a PC, not a dedicated gaming PC, but it has an i5 - 3470 with Intel HD 2500 integrated graphics, 12gb DDR3 ram, 256 gb C drive SATA SSD, 2 tb HDD and a Samsung Essential S3 24 inch Monitor (1920x1080).

I have an RGB Keyboard not Mechanical, but I think its Membrane.

An Evofox Gaming Mouse I got for 349, I forgot the model, but no mousepad but still have something which gives me decent substitute for it.

I need some GAMES to play.

Also I am broke so drop down some cheap, and I mean CHEAP GPU options.

Yes, I have headphones.
