Skip the Quadro FX 1800 completely: It is an extremely old and now-obsolete GPU, based on an old GeForce 9600 GS, with only 64 CUDA cores and a 192-bit DDR3 memory bus (versus 384 CUDA cores and a 256-bit GDDR5 memory bus on the GTX 560 Ti) - and with the FX 1800 avaiable with only 768MB of RAM, it cannot enable MPE's GPU acceleration feature at all even with the hack (MPE will be permanently stuck in software-only mode with the FX 1800, which can be as much as 10 to 20 times slower than hardware MPE acceleration). The successor to the FX 1800, the Quadro 2000, is based on only a GeForce GTS 450, with slower GPU and memory clocks than a normal GTS 450.

Thanks for info. I should have done more homework, sorry for silly questions. The Video Guys' DIY 7.7 build suggested the Quadro Fx 1800. Thought that would be reliable advice. So the GTX 560 is a ok choice or is there a better choice in price range.
all input is greatly appreciated
Since you're editing AVCHD, I'd suggest a 6-core i7 970 instead. You'll appreciate the added cores for processing AVCHD.
For the price, the GTX560 is very nice. The step up in performance is the GTX580 at more then twice the price.
