folks, for the last couple of days i have been trying to find out if there is a good reason for me to change my motherboard from a 4x AGP to an 8x AGP. i need a better video card so that i can play hd video and also play world of warcraft and i plan on getting the ati radeon 9800 pro. but my current motherboard only has 4x agp as i am using a ati radeon 7000 with only 32mb of ram. the 9800 pro is backward compatible but would i be losing much? i have been to tom's hardware and a couple of other reputable sites but i can not get any definitive information. can anyone point me in the right direction?
