Incidentally, I use the graphics card to be included in calculating public computing projects (BOINC, eg Collatz Conjecture). Performance-wise, can keep even the graphics card because it lacks, however, the double precision capability. However, one can not really expect that in this price range, so no drawback for me. Programmers will be pleased ATI Stream and OpenCL support the.
I had doubts whether the active cooling in my otherwise very quiet desktop PC is not too loud. But I was again pleasantly surprised: the fan of the graphics card is not to hear during normal operation in addition to a moderate quiet CPU / power supply fan. And in 3D mode you have to focus to the graphics card from the fan noise to hear.
For Silent computer I might still prefer the passively cooled version, but for the "normal" desktop it perfect.
