Actually, everything is better. The current tower has a newer, updated MB, with a better, faster processor, and it runs faster than the Dell, with less RAM. What Dell doesn't realize is, they have to continue to make parts available for their towers, for 10 years after they quit making the towers. What it all boiled down to, was Dell wanted me to spend another $600+ on a new tower, and I wasn't about to do that. I've gotten several phone calls from them, and every time they call, I get a different excuse from them. Dell has been known to use the cheapest parts that they can get their hands on, to build their computers, and when they have a mass failing of some of the parts, they chose to do nothing to fix the problem.
