If those are the 2 to choose from go with the hp. It has Intel quad process vs the other that has AMD. I used to be a big AMD Fanboy but they have missed the boat when it comes to Quad core. I just picked up a quad core Intel processor and it smokes!!! The problem you will have is that it is 64 bit vista. That means that some web pages may not load properly since not all add on installers will work with any 64 bit operating system. And NO OLD programs will install properly under 64 bit systems. By old I mean 1995 era. All those used 16 bit installers and will not load. I found out the hard way.
