Looking at your system specs again, you went from a Dell Dimension to an E-machine computer... E-machines don't necessarily use the best hardware for some things. While Dell back in the day wasn't super great on some of their computers, they were a lot better than the emachine pre-mades. You at this point, it is hard to say, but e-machines are worse than Dell Dimensions as far as gaming is concern. While the processor and video card are better, it isn't necessary going to make up in other areas that will bring it down if it is an emachine.
Again, run Performance Monitor and see what it says, as well as run WEI to see what it says for Disk Access.
