You and I need more friends. Who own BGA rework stations.
I was going to try my hand at it with a heatgun. I bought the stencil for the DDR chips a while back, and I have a donor card (a 5900XT someone mutilated by drilling their own mounting holes through traces - though I don't know for sure that the RAM is even good). Heatguns are too strong in terms of air force for very delicate work, but it should be able to do this kind of job as long as you tape around the IC with kapton tape so that the small components don't become desoldered and blow away from the force of the air.

I missed out on a 5800 Ultra that appeared on eBay a few years ago. It was an auction and I happened to miss it as it ended. It was one of the original review samples and came in a "cinematic" film roll tin. Maybe someone here is the person who won it. 😀
Keep your eye open in local ads for Quadro FX1000 or FX2000... Either are fine. Heck, the FX1000 does 400 core without breaking a sweat and out of my 5 FX1000s, only one has the "GC22" suffix ram, and the rest are GC1K, which means they do 800Mhz perfectly fine (The GC22 does 800Mhz fine as well).
You set Rivatuner to 'mod' the card to a 5800 with the 'straps' option, enable coolbits, and then overclock the 3D to 400/800 (leave the 2D at the regular clock). This way you can get a FX5800 for less than $50.
