Are these generally worth the extra few $$:
How does this work, does a manufacturer such as BFG, test all the cards that come off the assy line, then set aside the best over****ers, set them to higher clock speeds then sell them a little higher? I would assume you could get lucky and buy a normal card and overclock it similar or the same, but if you don't get lucky then your losing out on the extra % increase...
Couple other questions about these OC'd editions:
1. Are all the OC'd editions clocked the same?
2. Can they still be overclocked more?
3. What is the typical percent increase over a non overclocked edition?
