Come on, guys. Did I ask a stupid question? I just want to know if the performance difference between the 800 and 900 is worth the price difference. I assume that the huge price jump from the 900 to the 950 and 1 Ghz is more a status/supply/demand thing than a real difference in performance -- or am I wrong? I plan on using it in an Asus A7V w/ Crucial 128 CAS2 133, Asus V7700 GeForce 2 GTS, blah blah blah.
