Hi, I am going to upgrade my current X1900 XT card on my Mac Pro first gen computer. I've read extensively on this forum about the potential options for upgrading, but unfortunately many of them involve flashing and while I am very good with computers and upgrading things with hardware, flashing is not my forte, so I won't be going that route. It looks like my best choice is the Radeon 4870 512MB. http://store.apple.com/us/product/MB999ZM/A?mco=MTY3ODQ5OTY I don't want to pay 350, as that's WAY too expensive for a card, but what else is there? Unless there's a better option that I overlooked, I'll be getting this card. I do video editing and manage photos, so the video card is important. Are there any better cards that I'm missing? I also use Boot Camp with Vista 64 bit. I'd want to make sure the card works there fully also. I'm wanting to make the purchase in the next day or two. Thanks again for your assistance!
