I dont have any links right now but It was a thread started by a user named Onepagebook over at XS. People have the wrong idea that the xtra 512k cache per core is equivalent to 200 mhz speed difference. That is not the case. The only thing u will see the difference most apparent in , is SuperPi 1M test. Why ? Becoz instead of refreshing the on-die cache once , the opteron wont need to refresh it at all. But other than that , there isnt that much of a difference which would justify the additional price difference.
1M might make things smooth if u are HEAVILY ( ie. ten firefox windows , autocad , adobe photoshop , Acrobat Professional , winamp , divx open all together ) . But at that level , even 1M cache wont be able to do much and the computer will still be a little slow.
Opterons have a higher heat output than the 3800+ X2s as well. Not to mention they draw more power thus putting a little bit more stress on your mosfets. Factor that in with the 50+ USD price difference ,and you know you wont go wrong with the 3800+ . Most of the 3800+ X2s in the market , made after 0601 are doing great and can easily clock upto 2.7 ghz ( which is 100 mhz faster on each core than the FX60 , albeit at a lesser amount of cache ) . Save that extra money and get more ram for ur encoding. You will be just fine.
