Great! Thanks again Greatatlantic you were very helpful
too bad manufacturers name stuff more complicated then they need to ^^
Your motherboard is PCIe 2x compliant. The 7850 is PCIe 3x compliant. Basically, your motherboard will support the 7850 without a problem, but not at the maximum transfer speed of which the GPU is capable.
The card will work just fine and if you decide to upgrade to a PCIe 3x motherboard/processor in the future, you will already have a good GPU that will be fully capable in the new system.
Thanks markwp for the clarification
Never expected to get help so quickly, you guys are awesome ^^
