I have a dell 545st with Intel core2duo with 6gb ram. I am trying to add a graphics card to make it a dual screen. I bought ati radeon 5450 1gb card but the video performance is poor such as yahoo video chat, Skype chat etc.

I updated all the drivers from ati to directx to motherboard drivers but no improvement.

I thouhgt the ati card was in question but i tested it on a different computer with windows xp - it works normal and fine.

I tried nvidia bfg 8500 gt on the Intel core2duo to test the performance - but still no satisfactory results.

I am not sure what I maybe doing incorrectly. Can anyone help?

That is really strange, I would say RAM, but you have 6gb. For Skype and video chat, that would probably be your camera.
