Any thing cheaper than these cards might not have 2 DVI ports...
But if you get a 9400GT or 9500GT, ATI 4650, ATI 4670 cheaper than the above mentioned, then check if they have 2 DVI ports and if yes, get them...
well im running myself a 9400gt from EVGA ( 2 x DVI) on a dual 19'' lcd on my studio pc, im running Sonar 8 64 bits and it run smooth .. you dont need a powerfull card to run studio software. only cpu and ram. and for the no use of system ram ... you got 12Gb .. so dont worries about .. i got 6GB inside and even with the onboard videocard enable, it dont use alot of RAM. even in full band rec at same time ( 16 x XRL in ) the system dont use all the ram .
for the fan .. i use riva tuner to slow down the fan to 30% and it dont over heat. and its pretty silent.
i got a generic mid tower case with 2 x 120mm fan and everything is pretty cool
Its a new build so it does not have a card yet. My old machine has a matrox 550 which did the job fine - stutters on video, but this does not matter. I think you got too many fans there - maybe you could get rid of one?? One for the CPU one in the power supply thats generally enough for me.
well with a Quad core and 4 stick of ram ... if you dont have case fan .. hish .... it will be hot inside .. cpu temp will be higher than normal etc ... and both fans running on 5V .. so they run around 700-800 rpm .. so noisless, but make the job
and sorry i wanna know soundcard, not videocard , me im running 2 X Delta 1010 .. and wanna buy a third one
