the Nforce 2 oards have dual channel DDR, meaning that, if turned on, 2 identical sticks of RAM will share the data between them, effectively DOUBLING bandwith. It also has NIC onboard and some have 2 NICS. The onboard graphics are basically pointless, but it has just about THE best sound. Check thi sthread out. Someone that has one tells about it. http://www.aoaforums.com/forum/showthread.php?threadid=11033
that is for the EPOX 8RDA+. That is gonna cost about 130 dollars (already on pricewatch for preorder). It only has 1 NIC, no Video, no SATA, and no RAID, but the 8RDA2+ will, but will cost a lot. Unfortunately, the EPOX one isnt out to the public, but should be soon.
