I have a Dell Dimension 2400 with 2gb ram and Pentium 4 2.80 GhZ. I'm ready buy the Radeon HD 5450 PCI only LP for 94.99. Will this card work for the new games and will it work for Dell Dimension 2400? Please don't say go buy a gaming computer or buy a gaming console. I don't have money and I need to earn money for better housing. I am buying this card for my son's birthday. PS: Since I'm new and I can't post the link. It's on NewEgg.
