Well I am slightly nvidia bias soo i wanted some help with ATI's graphics since i really dont know much about how their product line works. I got a few simple questions about their products since I am lost in the world of ATI. So to begin the X1800 series could be compared to what series of nvidia? The 7800'S? What is the diff between the xl and the xt? is it just the higher memory on the xt? and is it like the 7800gt and the 7800gtx? And now for the X1900... could that be compared to the 7900 series? What is the diff between the x1800xt and the xtx? sorry its a lot of questions but i am building a new rig and i just need a video card and i dont know which one to go with and I am trying to keep an open mind about ati products.. but so far its between nvidia 7600gt, 7900gt, and ati x1800xl.
