Fast CPU with slow GPU?

I've searched for this, but can't find any answers. I recently bought an older Mac Pro. It has 2 x Quad Core 3.0GHz with 16GB of RAM with brand new SSD. The graphics card is really outdated though: Radeon 2600 (256mb)

Using OSX Lion, the cursor lags a lot and scrolling pages is not smooth. Even the simplest tasks seem like it's having a tough time keeping up. But when it comes to a heavy task, like rendering 4K video, it performs extremely well. I'm thinking the graphics card is the culprit, since all other specs seem to be great. Thoughts?

Thanks for the answer! Actually, it's a Mac Pro (tower) so the graphics card can be updated. Looking to get a Radeon 5770 (1 GB) Hopefully that'll speed things up.
