I currently have the Gigabyte GA-EP35-DS motherboard with a ATI Radeon HD 4800 series,since the card is really old and only has 512 mb of vram (gddr3 I think) I was thinking of making a huge leap forward by buying a GTX 970. Now since the card is pretty expensive on its own and I'm on a budget I was wondering can I slap that gtx on my motherboard and then later when I get some of dat money buy a Gigabyte GA-970A. So could that work?
