Why do you want a new CPU? ct1615 just told you the CPU is not the biggest problem here. The Graphics Card you have is very very low end. That's the problem.
If you go buy a 5670 or maybe a GTS 250 or 450 depending on budget then you should basically be good to go. Power source could be an issue so you can't get a really powerful card. The 450 recommends 400W, the 250 recommends 450W, and the 5670 recommends 400W so basically any of those cards will work fine.
i have two shitty ones and i need a cpu to run ff14 and i cant find one

I'd probably take the Core 2 over the Athelon, personally.
If you know how to fit things together, you can easily build your own PC. There's a lot of threads on good components for any budget. You could probably put together a quad core system for the same price as either of these. BTW, what price are you looking at?
However, if you feel uncomfortable with building your own PC, then either of these should be ok.
