just bought the wifey the following whiteHawk:
ASUS A8N-E PCIE MB
AMD athlon64 3700 sandiego core ( this thing will clock out to the FX-57 speed and not even overheat with regular aircool )
Corsair Extreme pc3200 2x 1Gig memory dualchannel
Hitachi 160 gig SATAII 3.0Gig/sec transfer speed 7200 rpm
Asus XA850PRO 256 meg DDR3 video whcih will flash to an XT version easily ( only diff is 12 pipeline vs 16 pipeline ) but the coreclock and other speed is 500+ /1020+
you can get the 850XT for just few bucks more, her's ( the 850pro cost 229.00 retail )
550 watt antec truepower with 120mm fan, which helps keep system running cool
under full load , running EQ2, TEC RPG, 3 different message proggys, and having webbrowser open surfing, it runs around 34c to 39c ( 39 max ) and doesn't faulter 1 instance, and nothing is running overclocked, is solid as a rock...... all graphics details maxed out to quality in every setting/game , yet she is running 1024x768 screen res at 85 mhz refresh rate.....
idle temp is 30 to 34 c......
the 850 is old tech by the current standards, but her whole system case included was built for less than 1grand, includes ASUS DVDRom, ASUS DVDRW (including RAM ), floppy drive 3 1/2 with 6 other card readers built in, new case with ducted fan for processor, using AMD heatsink & fan which came with processor in the retail kit...
also, the XT version has a cooling fan, ducted to thru the rear thru a pci slot, which helps even more disipaite the heat generated.....
just another opinion, could not see where there was much difference between the 7800s verses the 800/850 ATI versions that truely justified the cost increase.....
