I'm about to build my very own PC and need to know if I should get the r9/380 for my computer or any other similar graphics ca

Need help with deciding to choose the r9 380. Some reviews were saying that this GPU is really good but some say that they ran games not so well.

nah it doesn't say anything. it just says corsair cx 600w 80+ semi modular atx power supply

The CXs are intended for office use and light gaming rigs. They are not recommended for mainstream gaming builds.

I'm going with the EVGA 750W 80+ Bronze Certified Semi-Modular ATX Power Supply, it is a b2. Is that good?

Im still not sure about the compatibility note where it says my motherboard has an onboard 3.0 USB header , but my case does not have it
What are 3.0 usb headers. do i need them?
