in gta iv or a mafia 2 how many fps will i get with the 4670 ???? cuz these games will be the most i'll play ! no crysis etc.

I'm sorry I don't know about those games I only play the first person shooters like Call of Duty. But I would expect them to be playable.
Have Fun
Patrick

If you get a 4670 you won't be able to play them on high or ultras but you will be able to on medium at about 40+FPS.You should just get the 5670 it would do better.

gta 4 is a cpu heavy game but it also uses up alot of vram, so its 1 of the only games that you will see a difference in performance between a 512mb card and a 1gb card.

It is the same with Mafia 2,it's practically the same game it's just Mafia 2 is more updated looking and takes place in 1920's
