Hi, im thinking of doing a pc build with an amd fx cpu (socket am3+) and i have searched ebuyer (what i will buy from) for an am3+ mobo. however, the boards that i found only had pcie 2.0, even the higher end ones! i was wondering if a gpu with pcie 3.0 would fit in a pcie 2.0 slot. if it does then will it run at full speed??
Also, what does backwards compatible mean??
Thanks
 
Solution
Yes it will fit. It is backwards compatible. It means that a pcie 3.0 slot will work with previous version such as 2.0 or 1.1.
Pcie3.0 and 2.0 hasn't been much difference right now. You don't lose anything.
