Upgrade to PCI graphics card from onboard video


Oct 21, 2009
First off, I would like to say that my Dell has worked well for me for the past 5/6 years. Now that I have started to play WOW (never got into PC games before) and my wife has started to play other games like Peggle and Bejewled, I can see that an upgrade is going to be needed from the onboard graphics. I have decided to build a new i7 for me and my WOW addiction http://www.tomshardware.com/forum/273256-31-build and pass this Dell down to be her computer (I know, I am greedy). I would like to know what the best PCI graphics card would be for this setup. I do not want to spend $100 on a PCI graphics card for this old Dell but I do want something better than the onboard graphics. This Dell does not have PCI express, only PCI slots. The MOBO has a spot for an AGP socket (I guess the socket cost too much for Dell to solder one in) and the BIOS has an AGP option, Is it worth trying to solder in an AGP socket? Is full details on WOW at decent frame rates too much to expect from the PCI buss?

In a nutshell, I am looking for the best PCI (not Express) video card bang for the buck (price/performance ratio) that will work in my old Dell and any other upgrade thoughts to buy me some more time before I need to build another PC. I would consider a replacement mobo that could use all of the old parts, but I hear that the Dell layout is not std ATX and other mobos won't fit. Any help would be appreciated.
