I have two Windows 7 Pro 64-bit systems. Both with different i3 processors & different Motherboards. One system is using the i3's built-in graphics & on the other system, I've tried two different graphics cards; the Radeon HS 5450 & NVidia GeForce 210. With the Radeon card, text looked very blurrrrryyy. With the NVidia card, things look very grainy. I installed the drivers that came with the cards & updated the drivers to the latest versions, but things still look terrible. The W7 system with the built-in graphics, looks great. Any suggestions & what I can do to fix this? I certainly don't want to keep buying cards to see if one will look right. It's driving me crazy.
