Did you not read what I wrote? =/ All K8 processors are capable of processing both 32 and 64 bit instruction sets...K8 = Athlon 64, Athlon 64 X2, Opteron...therefore the 3800+ you've listed above will run both 32 and 64 bit applications and operating systems
You may want to look for the Opteron 165, performs roughly the same as the 3800+ but has larger L2 cache and should retail cheaper...of course they are hard come by at this point and time
The 3800+ is effectively two 3200+ chips on a single die so it will be fast so I will give it a thumbs up
PSU is fine
