I think the answer is absolutely not. You're comparing a crappy card from many years ago to a top of the line card from two years ago.
According to Wikipedia http://en.wikipedia.org/wiki/Nvidia_Quadro, the Quadro FX 580 is a GeForce 9500 derivative. The GeForce 9500 is dramatically inferior to a GeForce GTX 580 in every way. Here's a quick comparison of capability between the two cards (not comprehensive, but to give you an idea of how different these cards are): http://www.hwcompare.com/9390/geforce-9500-gt-512mb-gddr3-vs-geforce-gtx-580-3gb/. Here's a synthetic benchmark comparison: http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+9500+GT (and here's your FX 580: http://www.videocardbenchmark.net/gpu.php?gpu=Quadro+FX+580).
In either case, the FX 580 lags drastically behind the GTX 580 and no matter how much optimization you attempt to do to the FX 580, it will always be a card that has approximately 6-17% of the processing capability of the GTX 580.

I somehow mistaken this nvidia card for GTX 580. Welp! I'm now squeezing outlandish 8,5 k# out of it, but I feel it does her no good 
Is there any way to get it up to at least half of GTX performance?
