I have a geforce gt 610 graphics card which is not supported by The Sims 3 (the performance is not satisfying). I've read that radeon hd 6670 is supported by the base game and all expansion packs. But it's a ddr3 card and i have a ddr2 ram memory on my motherboard. So, my question is: Will my game work if I use that radeon graphics card because it's ddr3 and my ram memory is ddr2? Thanks in advance.
