My X1900's also have 16 pipes.<br />
It's a decent card as far I know. powerful. I think like the 'normal' X1900 (not XT, not XTX).<br />
You'll definately notice the difference. Not sure how well it overclocks.
X1900 AIW is a great card, the clocks may be lower but we're talking easy overclocking, with easy voltage boosts.<br><br>
Its got a full R580 core with 16 pipes and 48 shader processors with all the AIW functionality and a decent single slot cooler, they've also been selling for really cheap in some places.
