Which is a better gpu for the pentium g2120?

[That confused Badger]

I'm trying to build a budget gaming pc, mostly to run world of tanks acceptably on medium or high settings.

With an intel pentium g2120, should I go with the Radeon HD 7770 or is the Radeon HD 7790 worth the extra $20-30? Will there be a bottleneck with either? What framerates would you predict with either combo?

No there would not be a bottleneck with the hd7770 and i think,there would not be a bottleneck evenwith the hd7790/ Get the hd7790.
with either of the gpu's the fps would be greater than 45.
