I'm still running a Dell at work without problems. It's just the Dell version of the graphics card that requires the Dell version of the driver that doesn't get updated with each new release of SE. After a couple new versions, the video driver needs to be updated and Dell no longer "supports" it because they've moved on. Although the off-the-shelf video drivers from nVidia are great, they don't always yield the best results with a custom Dell video card and high-stress applications such as CAD.
I think if we would by a Precision workstation rather than the cheap office app computer, we'd have better times.
