Ill give you some good advice for vid card shopping.
-Go with at least 12 pixel-pipelines
-At least go with one with a 256Bit interface
-Pci-e is the way to go not agp
-500-1000mhz clock speed min
-256-512mb memory non negotiable
-Make sure it comes with a larger fan. If it doesnt; consider a vga arctic cooling fan.
-Dont ebay, always newegg.
