None of three models are SLI capable so you won't have any worry on that. Each has only one 16x slot. The MSI model sees not only the 1333/1066 memory standard over the Asus model's 1200 but is the only one with an nForce chipset while the other two are strictly Intel there.
The Asus board does see a 1600mhz fsb over the other two on further note. Here I've been running Asus boards and now have to consider a Gigabyte or MSI model for the next build due to seeing bad boards more frequently(bad caps, bad bios eproms) in the last few years when helping others as well as the first of two boards on the current build. Other then that these are about the top three favored brands to start with.
P5K, overclocking ftw
idk why PC Eye said none of them support SLI bc the MSI definitely does (at 8x like you said) but my vote is definitely for the Gigabyte. The ASUS is a great board, but the gigabyte has more PCI slots and more USB headers
The MSI model supports SLI but at a reduced caoacity unlike other boards seeing the 16x mode available. The idea behind SLI or Crossfire is to sync two cards together to see a performnance boost not to see a reduced capacity. That's where MSI has been lacking lately.
The Asus model used here has 3 pci slots while being an AMD model. If the third slot is needed or simply a sound card would take up one while two are needed empty there are PCI-E 1x sound cards for using that type of slot. Here the extra is needed for additional devices and why the M2N-E was the one selected.
While the Asus model sees the faster fsb there I tend to lean on the Gigabyte model since Asus seems to be slipping in the last few years.
no, asus model used here is socket 775, which is intel, not AMD
I mentioned that since the fact that the Gigabyte model sees 3 not 2 pci slots. When goiing to put the current build together the 3rd slot was something being looked at while maybe nothing of concern to dsella. There I was also looking at one or two ide channels and decided that one with 6 sata ports would be a preference over two ide with only 4 sata ports. But dsella would have to explain further on what type of build is being planned there. All we can do is point out the differences between each model until then.
