Ok, so now that ball bearings on my second 1900XT have worn out and the noise has started drilling into my temple, I've decided to upgrade my video card. I hear that the 8800GT is very quiet, but the Apple store is offering it for the jaw dropping price of $279. Did anyone ever figure out how to flash a regular PC 8800 GT into a mac-compatible one? I tried a search on these boards but never found a success story or a link to a rom. If someone could hook me up I'd appreciate it.
