I am looking into a new Dell. The Gateway that I have now is 7 years old so I am due for a new computer. The XPS 400 with most of the same components as the E510 is about $160 more. The XPS includes the Pentium D4 2.80 GHz, and the E510 includes the Pentium 4 3.0 GHz. The computer will be mostly used for word processing, internet surfing, photos and some music. Any suggestions? Thanks!
