yeah but... that still doesnt explain why the card blew...
he increased voltage from 1v to 1.2v and used stock clocks... and that blew the card? then the pwm seems to be pretty whimpy, no?
if it blows almost instantly with 1.2v and stock clocks, how safe is it to overclock the card and run it at 1.1v? how long until it pops?
overall it seems 6990 and 590 are very close to each other performance wise... enough to not care, each will do fine if you need that much horsepower... the advantage of 590 is that it has more overclocking headroom left... but it seems the pwm is kinda whimpy and cant feed the gpus when you actually push them? :/
for day to day users i think the 6990 is a better option... for enthusiasts the 590 is a better option but it looks like it will need better pwm cooling and some mods so it wont hold clocks back.
has anybody played with a 590 on cold yet?
can the pwm handle it?
EDIT: well, other reviews say the 590 is almost at the same noise level as a 580... and they didnt have any problems overclocking it with stock voltages...
in that case the 590 would be the better day to day card...
hmmm curious about more info on why some 590s blew up...
