I don't think your PSU will be able to run two 7870's. If I were you, I'd invest in a new PSU. Thermaltake can be a little unreliable. Try seasonic, xfx, corsair etc. I would recommend 800+ watts for two 7870's.

I don't think that the bottleneck will be a problem most of the time, but it could present itself as an issue with higher CPU load. I would consider switching to a FX 8320 (like an 8350 but stock clocked lower). Then I would get a second 7870. You can't expect a lot more performance without upgrading the rest of you system first.
