Does a gddr5 video card work in a gddr3 mobo?

My cpu is a HP p6703w if that helps. The regular memory is gddr3 so im assuming the pci-e x16 slot is to? Not sure. So far the best gddr3 vdeocard i can find is a geforce gt430 so im hoping to get better if possible.|||There isn't such thing as a gddr3 motherboard. You're thinking of your ram ddr3.



But yes, it will work since you have a PCI Express x16 slot.



VERY IMPORTANT TIP:

Definitely get a GDDR5 card and make sure it has a 256-bit memory bus width. It's 50% faster than GDDR5 cards with 128-bit memory bus width.



GTX 460 is a great card that's less than $150.|||No such thing as a GDDR3 mobo. At any rate your computer uses DDR3 RAM. But anyway the type of video RAM on a video card has no bearing on the kind of RAM the computer uses. They don't have to be the same. A video card with GDDR5 will work in a computer that uses DDR2 as system RAM for example|||Yes. The memory on a video card and the memory that runs your computer have nothing to do with each other.
