Source : XLR8yourMacA few weeks ago, we reported the possible return of the BTO ATI Radeon HD 3870 for the Mac Pro. Today, XLR8yourMac posts some very promising information. It is still rather a pity that Apple users are unable to get Crossfire or SLI support natively. As mentioned almost a year ago, "Apple keeps playing this nasty game of using GPUs from the previous generation, mostly for cost reason, making Mac users frustrated over time... without speaking of the lack of support for crossover or SLI on the Mac Pro while the hardware is ready to support both..." Rumor of Combo Mac/PC Edition Radeon HD 3870 in works - I normally don't comment on rumors and nothing official from ATI yet, but I've gotten word there's a Mac/PC (dual boot) Radeon HD 3870 PCIe card in the works, hopefully available at retail channels by the end of May. The card will be PCIe 2.0 but backward compatible with PCIe 1.0 slots. Here's a summary of the info I have on it: * 512MB of DDR4 vram (256-bit wide I assume) * Supports 1st gen and 2008 Mac Pros * Dual boot Windows/OS X (OS X 10.5.2 or later) * Crossfire supported when booted to Windows * Mac OS perf. said to be similar to Mac 8800GT (but remains to be seen) With the Mac 8800GT priced at $279, IMHO the Mac/PC 3870 will have to be priced at or below that card. (And every day that passes means more potential lost Mac Pro owner sales now that there's versions of the Mac 8800GT for both 1st Gen and 2008 Mac Pros.) Again no official ATI info on this mac/pc model currently, although they have (PC/windows focused) pages on the ATI Radeon HD 3000 series.
