i have a mobo that has a AGP 4X slot. Now i know a ti4200 is made for 8X slots, but will also work in a AGP 4X slot. And then there is the Ti 500 which is made for 4X slots, but will also work in a 2X slot. I preatty sure that the ti4200 has only slightly better specs the the ti500. But will my computer play games better with a ti500 then a ti4200 because it is made for 4x AGP slots? Or am i making a n00b mistake????
