Upgrading anything other than memory or hard drives in a Mac is ridiculously frustrating. Most of Apple’s machines use mobile CPUs soldered on to the motherboards, which makes swapping chips an impossible affair. And the ones that don’t use mobile chips have other supermodel quirks associated with them, like being lidless.
Upgrading Mac video cards has always been an unreasonable pain. Mac versions of PC GPUs have always been ridiculously overpriced and taken far too long to come out. Apple still sells an ATI Radeon X1900 XT upgrade kit for the Mac Pro, for $399. Do I even need to point out how disappointing that is?
Lately Apple has been getting a bit better with GPU releases. The 8800 GT and even more recently, the Radeon HD 4870 have both been build-to-order GPU options directly from Apple. Even more awesome is that once Apple officially supports a conventionally PC video card, it just takes one user to dump the ROM from the Mac version and now we all have a way of hacking PC cards to become Mac editions.
In a completely surprising move however, EVGA has released a GeForce GTX 285 Mac Edition. Prior to this release, all 3rd party video card upgrades were branded either by ATI or NVIDIA - Apple doesn’t really support the upgrade market the way the PC industry does. What EVGA has done is given Mac users a very high end GPU option that they can buy from Apple.com or through a handful of other online vendors.
Why do you even need a GeForce GTX 285 Mac Edition? The hardware is identical to what you get (for $100 less) when you buy a PC card, the difference is in the packaging and firmware.
These cards are only useful in the Mac Pro, but the standard video card in any Mac Pro doesn’t require any additional PCIe power connectors. If you upgrade to a more power hungry video card, you’ll need one or two cables that connect the small PCIe power connectors on the Mac Pro’s motherboard to the connectors on the video card itself. These come in the GTX 285 Mac Edition box.
The other change is firmware. In order to get your PC video card to work under OS X it needs firmware with a few EFI hooks in it. It’s not a huge change, but for whatever reason the PC specific cards don’t have it. Now you can do some Googling (or Binging) and find ROM dumps for various PC cards that will enable Mac operation, or you can buy a card that comes EFI equipped from the factory. EVGA is offering the latter, a GeForce GTX 285 with firmware that will allow it to POST and function under OS X without any modifications. It’ll also work just fine in Windows using Boot Camp. The price is a bit hefty at $449.99, especially considering that you can buy the PC firmware enabled GTX 285 from EVGA for around $330. The EVGA bundle does come with the two necessary power cables, which you’d have to buy separately if you were going the hack-your-own route; they absurdly retail for $30 a cable. The card itself has two dual-link DVI outputs on it; there’s no support for mini-DisplayPort so owners of the new 24” LED Cinema Display are out of luck. The advantage that the EVGA card has over the two current BTO options on the Mac Pro is that you do get two dual-link DVI ports, something that you don’t get out of either of Apple’s options. Furthermore, it’s quite disappointing that Apple doesn’t offer the EVGA card as a BTO option on the new Mac Pro - it’s easily the most powerful GPU officially supported by Apple, yet it’s barred from coming pre-installed on the most powerful Mac.
