They were good cards, yes. However, I'll recommend you save up to get yourself a new PC. On a budget, there are decent options around, that will most likely outperform what you have now. Old components, such as DDR2 are getting quite expensive, and it's much better to upgrade. I had an LGA775 mobo with PCi-e 2.0 and DDR3, but I don't think you can get those anymore. Just go through the forum and read some suggestions, there are lots of threads for people on a budget, looking to build a new PC, and if you ask there, people will most certainly help.
Edit: Try and get a buyer for some of the components you have now, to get a budget for new components.
