Bjorn3D - Every now and then companies will introduce products that carry no real change except for a product name. ATI have had few of those in the past, for example X1650 PRO which is a renamed X1600 XT. This is the case here where old X1300 PRO gets new pants and inherits a new name: X1550. It's an old IHV (Independent Hardware Vendor) trick to get rid of old SKUs and bring them back into the market through various channels. Believe it or not, product naming scheme does play a major role in consumers' minds. Potential customers will think this way: X1550 > X1300. Logically, 1550 is bigger than 1300; and because bigger means better for some people, why not go and buy it? I will spoil the fun just a little. In our case X1550 = X1300 PRO and have that equality running through your brain throughout this review, period.
