MSI is a brand I almost bought instead of Asus a few times. I think you could buy a cheaper motherboard. This supports SLI and you most likely won't use it unless you buy 2 video cards.
I would look at something like this, assuming it supports your CPU:
http://www.newegg.com/Product/Product.a ... 6813131391http://ca.asus.com/product.aspx?P_ID=YPZrr3KRcW3MBX5GI bought a 60$ Asus motherboard years ago and as long as you keep to the right brand, you shouldn't have problems regardless of price. The MSI board you picked is kind of more interesting for your video card as it has more room to breath, while the Asus one, the video card will lean over the first PCI slot which is not a problem so long as you don't need to add a PCI card, which you shouldn't need to with the current setup you told us about. This note regarding the Asus board "*Due to the chipset limitation, the AM3/AM2+ CPU runs at HT1 (1000MHz). " as me thinking more research would be needed to know if this is a problem. Regardless, I think you could save a good extra 20$ with a different motherboard that doesn't come with SLI support.
