My Fiancee has a Dimension 3000 that is a great little machine. The system has like a 2.99 ghz processor and 512mb Ram. The only problem is she is wanting to game now. I would like to avoid buying a new sysytem all together by hopefully finding a MB that will fit and take the same memory as the current system and then just buy a AGP or PCI-E video card and be done with it. may even upgrade her to 1.5 GB or Ram. I know this sounds stupid I am just trying to cut corners here and have not been impressed by what some have said about the PCI video cards.
