So i was doing some research and i heard that my motherboard was to weak for my CPU in addition my GPU is a 3.0 X 16 so i don't know if the GPU is backwards compatible so can you please tell me if they are ok.
PCI-E is backwards compatible. the number after pci-e just tells revision number, which sets maximum data transfer speeds. no gpu can really dilute PCI 2.0 at 16x speed as of yet. a 970 is a standard generally single card motherboard for AM3+(can be dual for AMD based systems, 970's are generally 16x/4x lanes). 990's are the step up
