    I've been looking at buying the ATI Radeon 4870 from a retailer such as NewEgg as I can get more video RAM and a cheaper price. However, I am concerned as there are PCIe power leads on the card that require hookups directly from the PSU. Has anyone bought a card that wasn't from Apple and had it work in their Mac Pro / can anyone help me out with this? It is an Early 2008 model Mac Pro.

    I don't know the answer to your question, but I highly recommend newegg for any hardware purchase.

    You can get the PCI power leads that plug directly into the motherboard (as it was meant to) from ATi directly. $14 a pop or so.


    Check the thread linked above, it will help you pick a card that has been flashed properly, will give you better luck!

    I'm running a HIS 4870 I purchased from newegg and Flashed it to the correct bios in a 2008 2.8x8 MP on 10.5.7. Picked up the PCI-X power cables from ebay - some reseller from HK.

    Everything works fine except: there is an issue with waking from sleep on occasion where the Dell 3007-HC is not getting a good DVI signal and needs to be power cycled. I also see an occasional "Hiccup" in the graphics. I think these issues are related to the pre-release 10.5.7 as I see the Hiccup on my 3870 at home. Beyond that, running 2560x1600 and 1152x2048 displays just fine.
