Upgrade CPU or GFX

[Invaliduser]

just a quickie all, current system is:

7850BE
4850 512Mb
4Gb PC6400 OCZ reaperX
(other stuff)

im looking to upgrade either CPU or Gfx card shortly. Can I ask for your thoughts on which of the following options would represent the best choice please..

1. AMD Phenom x2 955BE; or,
2. ATI 5770

Im interested in knowing if either would be bottlenecked by the remaining part (ie, new cpu bottlenecked by old gfx card; and vice versa)

cheers.
