Video card help

Hey, I want to get a video card for my computer because the integrated intel one sucks. I know that some cards play better with different processors.

So this is what I have in the case.

1. eMachines T2596
2. Intel Celeron running at 2.6 ghz
3. 256 mb DDR SD ram
4. 60 gig hard drive@7200 rpm
5. 3 PCI slots (no agp or pcie)

I think thats all that you guys really need to know. If im leaving something out please tell me. Remember that the card NEEDS TO BE A PCI CARD and I cant upgrade my processor or my motherboard because of my warranty. And over time i will get a stick of 512 mb of ram.

Problem is, all the pci graphic cards suck. pluss your using a celeron and only 256mb of ram, not the ideal machine to play games on. ATI has some older gfx cards that are PCI that are ok, go check at www.newegg.com to find a good PCI card.
