My motherboard is Asus M2N32 64,and i would like to know if these graphics card fit in my slots.I also have a huge cooler,the asus silent knight 2 sitting on top of my AMD processor.I do NOT want to buy a card and not be able to fit it.

^+1 the Powercolor 4870 is clocked higher than the other 4870. I choose that one.

Realy??Better than all of those huge cards with twin fans?

Yeah the coolers don't make them run faster. It helps if you plan to OC though.
