New video card for an old PC

[akaSM]

Remember that PC I tried to use to make us a TF2 server? Remember how much it sucked? Well, the poor thing has a really weak video card (a geforce 7200gs), since my bro and sis like to play games, I'd like to get a better card for it but, here's are some objectives:

• Price doesn't really matter
• It's got a 400w power thingy (was it called a PSU?)
• It's got a Pentium D processor @ 3Ghz
• The motherboard is a Intel d102ggc2
• It's got 1GB of RAM

Now, with those things in mind, which video card would be a nice idea to get? Specially considering that the motherboard won't accept RAM beyond 2GB and the processor isn't exactly powerful. I don't want to end with a extremely expensive card that will be limited by the processor >_>

The games it'll run will be mostly what we play in the NPF weekends. You can take TF2 as the reference game.

Thanks in advance .

Oh, if possible, list various options like

• card A can run TF2 fine but, that's about it
• card B is more expensive but, will run more things
• card C is the best you can get for that processor
• card D is good but, your processor sucks and it'll limit the card
• card E is what you need but that power thingy is too weak for it
