Anyone want to explain why they can put the memory in this card higher than my 7800GT? Seems like a cheaper card wouldn't have as fast of memory...

i think nvidia owns the high end all the way to low end
but not the ultra high end
it is true that the 7800 512 gtx > x1800 xt
but you can hardly find a 512 gtx now if there's any
and the x1800 xt's price are generally dropping as well

The X1600XT uses 128bit GDDR3... the GT uses 256bit GDDR3. Thats why it gets out performed by the 6800GS at almost all benchmarks.

Yup. 128-bit saves a lot of traces on the PCB; its a much simpler and cheaper design to implement, so they can afford to put very fast GDDR3 in there. And they need to, since 1400 Mhz GDDR3 @ 128-bit is just like 700 Mhz GDDR3 @ 256-bit (that's like what the 6800nu had).

Um yeah... this card is cheap because it should be, not because it's a good deal. So, what comprises the ATI mid range now? The X800XL through X850XT range?

Almost like a 256bit system running at half speed. I mean take a look at the 6800 vs the 6600GT. The 6800's fill rate was 3900 and the 6600GT's was 4000. Potential memory bandwidth for the 6800 was slightly highter than the 6600GT, but despite all this the 6600GT regulary outpermormed the the 6800.
