Decent card for my HD6570 replacement

[newapprentice]

Hi Guys,

I am planning to repair my old PC and give it to my niece. It has a gigabyte H61M-DS2 motherboard (LGA 1155), pentium G630 2.7 Ghz dual core, 4 GB RAM and Radeon HD6570. besides the graphic card everything is working fine. I would like to ask advise for decent graphic card replacement. I managed to find small PC shop that still has some i3 and i5 with LGA 1155 socket, but still hasn't decided on graphic card. Please note the card size is limited with space available (169(L)x19(W)x94(H) mm for card size) and my niece (and her father) will probably use the pc for game.
Much appreciated
