Upgrade compatibility, GPU
I am upgrading the graphics card from an old computer, the current card in it is an Nvidia card that has 1/4 gig of memory. after doing some research i have found that the mother board is said to be compatible with the Nvidia 9 series. But the card i have is ddr2 and the one i found is ddr3 but is of the Nvidia 9 series, as is my current one. It also has the same plug in. Does the channel matter on GPUs? My mother board has the serial number D946GZIS.
