Hey gang, I'm try to replace my video card in my G5. However, I really don't know about compatibility with Macs, so hopefully you can help! I found this card, and I think it will meet my needs. Will this work with a Dual 1.8 G5? Also, does this mac has a 6pin connector to power the card, or will the card be self powering? If you need any more info, please ask. Thank you in advance! *edit* if this is better suited in the mac pro/Power Mac section, I apologize!
