I think it will not work to it's full potential. You will have to wait for someone with more knowledge.
Your motherboard has a PCIe 1.0 slot while that card is PCIe 3.0
To my knowledge they are backwards compatible which is why I originally replied yes, but I'm not sure if/how many problems you would encounter or what the performance drop would be like.
Sorry I can't be of more help.
