Will the Radeon HD 5450 Low Profile PCI only work good on new games?

[MrCoolguy]

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.

There would be no problem with the card playing new/old games, given appropriate graphics settings, but I'd be much much more worried about the processor.
You'll want to check with someone else but I would suspect that the powersupply won't be enough either.
