Not sure about good PCI graphics cards but one that caught my attention was the PNY Geforce 8400GS for many reasons:
It's on Play so easy and trustable to buy
PNY is one of the better companies that make GFX Cards.
It's £40 which isn't a lot.
Though memory doesn't always matter, 512MB is pretty high, obviously performance is lower because it's not a PCIe card.
Either way, I'm just buying this to be able to play sub-par games with decent looks and framerates. I have a PS3 for a reason
