Looking for an upgrade in video card

[Patricio_1]

Hey! since i got a ps3 a years back I loose track on builds, rigs, and pc parts.

I currently got:

AMD A6 3500 2.10ghz
ATI Raddeon HD 5450
Power Kellyx 500w
ASRock A55M-VS

I wanna upgrade my video card, I dont want something fancy, just something that can keep a good run with League of Legends, currently I can play it in 720 medium settings (60/100fps)

What should i do?

If this is your PSU: http://www.bahiapc.com.ar/fuentes-de-alimentacion/fuente-kellyx-500w-con-cooler-de-12cm-en-caja/
... I would not trust it with too much card. That is what we call a 'fake 500W'. I doubt it even has a 6 pin PCIe connector.

Your best solution would be a GTX 750 Ti that does not require any external power.
