They are both good cards but good god do you need an i5 to replace your Celeron.

Their very close depending on the games you play but your processor will limit your results.

I was thinking replacing the cpu later with a AMD FX6300 ,and the games i play are BF3 and some other fps'

Also I am not a rich person to go with expensive CPU's,motherboards and other parts.Mostly I want to buy a good graphics card and then a CPU and so on
