You won't have a problem buying from a good online store. Unless it's been setting for years in some rinky dink local store like the other person said you should be fine. I've literally never heard of anybody having a problem running a Vishera in any modern AM3+ motherboard. And yeah worst comes to worst just buy the cheap sempron cpu to flash the new bios
edit: That's a really cool looking new MSI AM3+ motherboard. Weird for them to even come out with a new AM3+ mobo though, thought that socket was dead?
If I build an AMD pc I'll probably def use that mobo, I like how it looks. I think alot of the AMD mobos look ugly >_>
Came out back in June,

Actually has good SLI support, that MSI g46 board has SLI but has horrible reviews on newegg. This new MSI seems good and supports 8x on both slots in SLI/Crossfire
