Are there any known issues with motherboards not being compatible with DDR2 graphics cards? My old Socket A motherboard just broke down and I have to buy a new one; I was wondering if my nVidia 6200 256MB/64bit AGP8x(DDR2) will work with just any new Socket A board. I didn't work with the old mo-bo; I have heard that some motherboards only support DDR and not DDR2(or DDR3, for that matter). If there are some compatibility issues then I would be better off buying a new CPU and board to go along with it, not to mention a new GPU as well. It would probably also make sense since I had brought the 6200 to the shop where I bought it to have it checked because it didn't work; they said it had no problems. I was forced to buy a new, lower spec card to be able to get the PC to work. I had no problems with a 5200 128MB/128bit card working, until my PC broke down a few days ago.
