|"what else do u need?"|
We need the model & model number. The number you gave is useless & comes up with zero hits on Google. We know you have a Dell & I assume it's a desktop. Is it a Dimension, Inspiron, Optiplex, Vostro, etc? And what is the model number? It should be right on the front of the case. If it's not, look for a label in the back.
BTW, the chances of finding a decent gaming card for $30 are pretty slim, unless there's a sizeable rebate involved. And you may need to upgrade the power supply too. If your system has a PCI-express slot, the following article will help. If it has standard PCI or AGP, the article is pretty much useless, except for maybe the Hierarchy Chart at the end of the article.
