I have a gigabyte ga-m57sli-s4 and I was looking at going to an AM2+ processor at some point in the future. Have to figure out other problems first. I know the board will "work" with the newer AMDs but Gigabyte says: (Note) If you install AMD AM2+ CPU on AM2 motherbord, the system bus speed will downgrade from HT3.0(5200MHz) to HT1.0(2000 MT/s) spec; however, the frequency of AM2+ CPU will not be impacted. What does this mean exactly? Would a quad or tri with this impact act any better than my x2 5000 black (currently OC to 3.1). Do I need a newer board to run these in any way that will show gains. I guess the main reason I'm asking is that Vista says my CPU has the lowest performance index of any of my parts. Like your thoughts. Thanks.
