Looking to up grade

 I am looking to upgrade I want to get a new video card at right now I’m running a r5770 hawk. I’m thinking about going with two 650 boost it

Also looking for a new power supply.

tell me if you think or if there is a beter card for my build

If you have a choice of one card vs two GET THE ONE CARD it's always better not only for compatibility but for framerates as well.
