Will a phenom 560 x2 have bottlenecking issues with 5770 x2?

Just got this rig together:

Asrock 870 extreme3 mobo
Phenom 560 ii BE x2 at 3.3ghz
4g DDR3-1333Mhz
Galaxy 240 gt 1g
430w psu

I'm wanting to drop a 5770 into this rig sometime in the future (using my current vid card from my older system). I know the psu will need to be upgraded, but my mobo supports crossfire, and I was wondering if having 2 5770's would cause a bottlenecking issue with the CPU (I'm pretty sure a single 5770 will work for me, but I'd like to be able to upgrade it in the future if I need to)

I can unlock the other 2 cores on this processor, and it seems to be stable, but at the moment, I'm keeping it dual core to be on the safe side.

  1. If it's stable as a quad than I would say no it won't bottleneck, if its stuck as a dual core it's going to choke on a number of newer games that like more cores.
