i havent read much about the PS3 lately. they keep changing it!

what is the difference between the modes? would this ever be used with say a game itself? And why by increasing the mode allowing larger/faster data transfer does this make it slower performance wise?

I believe DNET (RC5-72 and OGR25) has true 64 bit clients. but it is down at the moment due to a RAID crash. It should be back soon though!
