For most "general usage" there is no real advantage to spending the money for either, both offer much more CPU power than you'll ever need.
It's only for applications that actually load the CPU, like playing a game or encoding an MP3, that you should care about benchmarks.  
The fact that one can process 10,000 keystrokes a second in MS Word doesn't really make it better than one that can only process 5,000.  Even something like MP3 encoding only matters if you actually do a lot of it.  
My music server has a "slow" Tualatin 1.3 GHz processor that takes ten minutes to rip and encode a music CD.  But since I only buy a  couple of new CDs a month, I'd get almost zero benefit from buying a 3 GHz CPU to reduce the rip and encode time to 6 minutes for just 2 CDs a month. 
	
	
		
		
			Well, if the intel processor has hyper-threading then it has a real advantage over the amd processor, at least in general usage as you define it.
		
		
	 
 that's true when/if any one task is heavily loading the CPU.  Having a bunch of essentially idle applications doesn't really favor one over the other.
