Yep, I know they're not cheap. $100 at newegg for a radeon 4350 on PCIe 1x. I think the Invidia 9500 for PCI was about $30 less. I was just curious whether there was enough advantage to the PCIe 1x to justify the price difference.
If it weren't for the damn backwards mobo in these Dells I'd just replace that!
