Any GDDR5 cards?

[iModFrenzy]

I have a desktop that I plan to upgrade but once I upgrade it I will have a Radeon 5670 512mb GDDR5 lying around so I was wondering if I could use it in a G5 PowerMac.

No, you cannot use that card in a PowerPC Mac.

No. Stop the misinformation. That card would work fine under Linux.
