I see, that makes sense from reading the specs.
What exactly are the differences between the X1800XT and the X1900XT? I see that the X1900XT boasts 48 pixel shaders(the X1800XT doesn't imply this), but besides that i don't see any difference between them in speed or other specs.
Any new technology improvements i'm missing?
Doesn't X1800XT have a slightly faster memory than X1900XT (1.5 ghz vs 1.45 ghz)?
