Hi all, A few days ago my Early 2008 Mac Pro's ATI 2600 bit the dust, so I need to get something to replace it. I spent several hours last night reading info on various sites about what my available options are. I'm finding that most pages either 1) have conflicting information with other sites 2) seem incredibly outdated or 3) seem sketchy in general. I don't want to drop a few hundred dollars on a card that won't end up working. From what I gathered, the NVIDIA 8800 is the "safest" upgrade for my model of Mac Pro, in terms of how likely it is to work without problems. However, it seems that this product is no longer sold by anyone except NVIDIA on their own site, and they charge almost $300 for what is now like a 2 year old card. I'm reading that some PC cards can be flashed to work with OS X, and while I'm wary about having to do anything that's likely to give me problems down the road, it seems like it would open me up to better options on a card, as the ones that are specifically made for Macs are few and dismal. Does anyone have a web resource with easy to understand, reliable, current information on what graphics card upgrade options are for an Early 2008 Mac Pro? What I'm really looking for is something with a list of all cards, both PC and Mac, which are known to work with this model and what is required to get them working, if they don't right out of the box. I don't have the money to spend on the ATI Radeon HD 4870 or EVGA GeForce GTX 285 that Apple currently sells themselves as the only upgrade options. It seems like I could get something with perfectly fine performance for a fraction of those costs. Thanks in advance! P.S. As far as how much power I need, I will be doing some 3D gaming, but nothing too crazy.
