I recently bought an Nvidia 9400 GT graphics card 1024MB DDR2 and it has given me nothing but problems. It's causing overheats, the fan isn't working, it seems to not be compatible with KO, and it's causing cooling issues with my cpu. It could be a faulty unit but I'm returning it and getting something that is known to run smoothly with KO. Does anyone have any suggestions for a graphics card? Price range between $100-$150.
