I'm used to working with MSI Mobo's and both boards you give up here are excellent. However, I would recommend the K8N NEO (go for the Platinum if you can get it). Not because of a big difference but I always liked the Nvidia chipsets better then the VIAs. Call it a personal preference or not but Nvidia somehow seems to be a wee bit more stable then the VIA chipsets.
Is it a bad thing if there is smoke coming out of my case?
