Graphic card around 100-120$ (Gaming)

[tapilogali]

I am currently looking for a better gaming card (currenlty have ASUS eah3450, which is completely useless.)

I have Gigabyte GA-MA78GM-S2H motherboard, some cheap LPK2-23 400W PSU, AMD Athlon 2x 4850e (2,5Ghz).
(+ LG 23" IPS Led monitor)

I mostly play League of Legends, Runescape HD, Warframe, Tera Online, but my FPS is terrible atm. (ofc. it is)

Been searching for 1Gb GDDR5 128bit cards, but there are sooo many, i have no idea which one i need really.

Waiting for answers
