New motherboard problems

I recently just installed a new mother board in my gaming computer and i am finding that i cant play games at the setting that i use to or even watch a 1080p video with out it skipping frames. If anybody has a idea as to what is happening any help would be appreciated.

What is the motherboard and other system specs? Did you do a clean install of Windows?

MSI 970 Gaming AM3+ ATX RTL

AMD Phenom II X4 965 Processor 

16 Gigs of ram

Nvidia 650 GTX TI 1GB

Windows 7

Check to make sure all you're temperatures are good. Check and make sure all your drivers are up to date too.

A fresh install of Windows is usually advisable when changing motherboards.

Ok Thanks!
