thanks for explaining the differences gomer

i went out and bought this one because my comp doesnt have a PCI express slot in it Just a Standard PCI. Its the best one best buy had that was in my price range
ill probably install it today and ill post how much better it is. I'm imagining that it will blow my current vid card (which is a Nvidia GeForce MX 440 64MB, and this one is a 256MB DDR).
