Greetings,

  I've been working with 2 different Dimension 530s I purchased in a surplus auction.  The first problem I encountered was a graphics card issue.  Using a nVidia RIVA TNT2 64 that has TNT2 VANTA printed on it, I was able to see that the computers run fine.    I'm not using them for hard-core gaming so a high end card isn't necessary.  My question here is what type of graphic cards can I use in the AGP slot?

For one 530, only a single 2.4 Ghz Xeon processor is installed.  I want to get another matching processor at 2.4 Ghz but I'm not sure what specifically to look for.  I know it's a socket 603.  I found this one on eBay:

It has a little HP sticker on it but the front bus speed and L2 cache match the existing one.  There is a pair of identical ones like this available for like a $1 more.  What processor do I need?

Thanks!
