DDR3 and GDDR5

[randomgameronlinux]

My memory is DDR3 and my motherboard supports DDR3 as memory but does it support a GDDR5 graphics card?

Yes.

It doesn't matter what RAM your motherboard supports, it has no effect on the graphics card. BTW, GDDR5 is of the same generation as DDR3, yet they are completely different, what a CPU needs from RAM is not the same as a GPU needs.

Let me put it in this way. Like how your CPU needs RAM, your GPU also requires some memory(in your case, GDDR5 memory). So the whole graphic card by itself is a separate Graphical processor which utilises GDDR5 RAM as its memory for graphical processing. The GPU communicates with your CPU via PCI express bus. So CPU and GPU(both have seperate memory for each other) are two separate units which communicates with each other using CPU's PCI Express bus. So the GDDR5 memory is used by your GPU and it is local to the GPU only and it is not related to your Motherboard's RAM compatibility.

Your motherboard(which supports DDR3 memory for your processor) will support a GPU irrespective of its memory type(which has GDDR5 or GDDR3 memory for GPU), if it has a PCI Express slot.
