[opensuse] Slowness since video 3D

I recently enabled 3D support for my video card (intel i845) and "Desktop Effects" in control center. Every since then, firefox2 does not scroll smooth, it is "jerky". Also when clicking on apps, they open but are initialy black then load the interface. I know this is hard to explain but i am wondering if it is a video card slow-down? I am thinking about getting nvidia 9750 ultra. I am not gaming, just want good 3D support and maybe fix the slowness problem.
