I was recently thinking about upgrading my graphics card from my GTX 460 to something like a 650 and went to Microcenter.com to check out the products available. I found that their are minimal amount of choices for video cards as mainly everything they had was DDR5. So I started looking at motherboards and found that all of the ones I saw were DDR3 boards. Can you use a DDR5 card in a DDR3 board? I'm still a newbie to building pc's all help is appreciated.
