Chris,
It should work for the Phenom out of the box. For the 5770 though I do not have a solution. That XFX card is not reference, which means nothing out there (that I know of) will fit that card PCB. The only option you have is to sell your 5770 and get another card if you want to liquid cool it, or, wait and see if EK comes out with a solution that will fit it.
Note the MCR-220 radiator in the kit would do better if a 3x120 rad of some kind were in its place, or each heat source was on its separate loop. Having said this it will still work and be superior to air cooling, and quieter.
Best Regards
