my config is as follows :
amd fx6300
msi 970a g43(ddr3)
I want to upgrade my graphics card,will msi 750 ti gb ddr5 graphics card will support my board,as board is ddr3 supported.
all that matters is if your motherboard has a pcie slot, and you have a power supply capable of powering the video card.
also make sure to check if it is a 750 ti that needs additional power cables.
motherboard ram has nothing to do with the video memory
