I have this one, it works great.

I have the MSI, my friend has the ASUS. Of the two both will give you the exact same preformance. The MSI costs like $15 less, has a far, far better layout, and has SB Audigy built in. The only real difference is the ASUS has 8 phase power so it can go up to extreme overclocking while the MSI is only capable of high overclocking. In your case this is a mute point except for the power problems this brings. The 8 phase power in the ASUS really sucks the watts my friend had to upgrade his 600W powersupply to a 680W powersupply to handle this and two 7900GTXs when his system had enough power with the 7900GTXs before he upgraded the motherboard. Now for the layout. There is nothing in the top slot on the ASUS board, so you only get six slots total. If you use dual solt video cards they block all but one PCI slot, which is right between them, so installing anything restricts airflow to the top card. The bottom card ends up right on the bottom of the case so airflow is restricted there too. With any long videocards (such as the 7900GT) several of the SATA ports get blocked on the ASUS as well as the clear CMOS jumper. On the MSI the SATA ports are all along the far side where they do not get interfeared with and the clear CMOS is an easy to reach button instead of a jumper. The built in Audigy SE on the MSI means you don't need to add the X-Fi which is only slightly better, most people won't notice the difference going from Audigy SE to X-Fi, so this can save you like $130. the ASUS also has some BIOS issues, related to the SLI X16 settings, read about them on Xbit. The ASUS only gets four eggs on Newegg and the MSI gets a full five. I recommend getting the MSI and saving the money on the X-Fi. Put that into 2GB of RAM (1GB of RAM = BAD, 2GB of RAM highly recommended) in a 2x1GB configuration. I also have two 7900GTs running in SLI on this board, they work great. Get the EVGA 7900GT KO, mine are each overclocked to 570MHz/1720MHz. For more info on 7900GTs click on the second link and read my post here.

PM me if you have any more questions as I have worked with both the MSI and ASUS boards (as recently as last night) troubleshooting issues and I will help you decide which is best.
