Well in that case a 980 would be the fastest Quad Core You can get that isnt overclocked but leaves room for overclocking, but Most would Recommend the 955, 960T, 970, 975 before the 980.
If you dont want to overclock heavily a 970 would work. Now I believe the 970,975 are Thuban Core Parts like the 960T
if you can find a 1090T or 1100T go for it.
Otherwise in order to get performance levels of the Phenom II stock or overclocked in the Bulldozer FX youd have to heavily overclock them as their Single to Quad Threading is lacking

So Im assuming youd pick the Phenom II then over the FX.
Because In reality there is always a bottleneck no matter where you go because of physical limitations of all computer parts.
You can always overclock the Athlon II but you will have to do it via the FSB because the multiplier is locked from going higher.
Id recommend Coolers from Cooler Master or Thermal Right for any CPU out there right now

For CPU, yeah high end Phenom. Once you hit 3.6/3.7Ghz with the Phenoms the system really feels snappy.
But, have you tried clocking that 645? Those Athlons were not bad clockers. If your HSF is decent, could probably gain enough performance to hold you over until you could afford Intel or Piledriver...or whatever else comes up.
Hell even at factory speed they are snappy. My Bro has a 555 BE unlocked to a 955 BE and its quick with a 6770 (Yes its a Middle Ground machine with 64bit windows, built by myself n maintained
