Nvidia 8800GT Card
Oven-Bake/Solder Reflow
Tip (Feedback)
(Apr 2012) A few more positive reports on the "Oven Bake"/solder reflow fix (example youtube video) for some Nvidia 8800GT card problems in Apple's Mac Pro forums. Some earlier/older threads on Nvidia 8800GT card problems have updated posts (here and here) on the oven-bake fix. As always, YMMV. (Some owners had also tried older tips on removing dust buildup, redoing thermal paste, SMCfanControl to boost case fan speeds for better cooling, etc.) I was skeptical when I first heard about it but oven baking posts in Nvidia's forums go back to 2010. Be aware DIY 'reflowing' the solder balls is often not a long-term fix. (It's been used on other chip problems in AVRs, etc. but the solder joints typically fail again.
Reader Feedback on Mac ATI 5870 graphics card
(Dec 2011) Replies to a reader request for Mac 5870 user feedback from longer term use. (i.e. any app or OS issues seen over time, would they buy again, etc).

2009 Mac Pro owner running GTX-285 and ATI 4870 Cards (via Aux power Y adapters)
(April 2010) Comments from a 2009 Mac Pro owner on using both an Nvidia GTX-285 and an ATI 4870 graphics card. (By using Y adapters off the Mac Pros 2 Aux Power Connectors, since each card requires 2 power connections.) I know in the past some Mac Pro owners had used ext PS or adapters off the PATA Optical drive connections in pre-09 Mac Pros. And yes, he knows that apple lists 300W Max for the PCIe cards in the manual.
