I have a Sawtooth G4/500 that I'm looking to upgrade to Quartz Extreme capability.
I've been reading the Strangedogs forums, but am now having trouble deciding exactly which card will work for flashing.
I'm looking at GeForceFX 5200's because they're cheap and will also support Core Image.
I could also use Radeon 7000's and 9200's as well as some older GeForce 2/3 cards.
Dongles for macbook air. What I'm trying to work out is if those cheap $35 GeForceFX 5200's on NewEgg will flash. There are so many, I don't know which one to get.
Any experiences or advice welcome.

FREE Shipping on orders over $25 shipped by Amazon. Please be aware that while the 3,1 Mac Pro has the same GPU compatibility as the 4,1 or 5,1 that the older hardware of the 3,1 will result in some comparative bottlenecking. In general I recommend the GTX 770 as the high end for the 3,1 Mac Pro as it maintains its price/performance ratio.
