We have had no problems running it in our 2008 Mac Pro 3.2GHz. We asked ATI about this issue.So heres the 3D Game Shoot em up for all the cards compatible with the early 2008 Mac Pro 3.2GHz 8-core monster.BLIZZARD WORLD OF WARCRAFT Working with a WoW programmer, we devised a test that stresses the GPU and produces repeatable results.He started at the totem pole at the entrance to Village Narache, ran East to the two large trees on a nearby hill, turned around, and returned to the totem pole.
By using an addon called Titan Performance, we were able to capture average frame rate for the running sequence. Ati Radeon Hd 2600 Xt Pro Full Screen ModeTest was run in Full Screen mode and best settings.) MACSOFT UNREAL TOURNAMENT 2004 FLYBY We used the SantaDuck Toolkit to benchmark with UT2004. Though a Botmatch simulates actual game play, it is very CPU intensive. However, the Flyby benchmark is primarily GPU -- especiallly at max settings and high resolution. ASPYR PREY It represents for the games based on the Doom 3 engine. ASPYR QUAKE 4 We had trouble getting version 1.42 to run its nettimedemo so we tested version 1.3 instead using iddemo001. ASPYR DOOM 3 Holding the Command key down at launch allows you to set the resolution to various sizes not available inside Doom 3s interactive settings. LEGEND of GRAPHS FX 5600 nVIDIA Quadro FX 5600 (1536MB of GDDR2 - Apple CTO) G8800 GT nVIDIA GeForce GT (512MB of GDDR3 - Apple CTO) R1900 XT ATI Radeon X1900 XT (512MB of GDDR3 - Apple CTO 2006 Mac Pro) R2600 XT ATI Radeon HD 2600 XT (256MB of GDDR3 - Standard card for early 2008 Mac Pro In the case of each 3D accelerated game, we ran at High or Highest Quality settings at 1920x1200. All Macs were running Leopard 10.5.1 with the Leopard Graphics Update 1.0 installed. CONCLUSION As a 3D accelerated GPU, the GeForce 8800 GT looks like a great addition to the early 2008 Mac Pro. Its significantly faster than the two Radeon options and at 200 CTO, its a no-brainer. The advantage should also apply to pro 3D apps that use 3D OpenGL code for animation. However, its a different story with pro apps that use Core Image effects. For that info, we refer you to our expanded page with Motion 3 and iMaginator test results. PROBLEMS WITH DVI-2 PORT Two of my remote mad scientists reported either slowness or errors when they used the DVI-2 port on the GeForce 8800 GT. Ati Radeon Hd 2600 Xt Pro Driver Or FirmwareHopefully this and the Core Image performance will be addressed with a future driver or firmware update. LEGACY 8800 As you probably know by now, a collective groan was uttered by many of the 20062007 Mac Pro owners when they learned that the GeForce 8800 GT kit for the 2008 Mac Pro was NOT compatible with the older Mac Pros. As of April 15th, 2008, Apple started shipping the legacy version of the GeForce 8800 GT in a kit form for 20062007 Mac Pro owners. When you visit the Apple Store USA, click on Displays in the left column and look for the Geforce 8800 GT labeled 1st Generation. Let me remind you that our testing has shown this to be a strong 3D OpenGL gaming card but a weak Pro App card (Motion, Aperture, FCP). Ati Radeon Hd 2600 Xt Pro Mac OS X CompatibleWe believe a Mac OS X compatible Radeon HD 3870 would perform better for Pro Apps. We are urging ATIAMD to release such a card and will alert you if and when that happens. MAKING THE RADEON X1900 XT WORK Some reports have come in that the Radeon X1900 XT does not work on their 2008 Mac Pro. We have had no problems running it in our 2008 Mac Pro 3.2GHz. We asked ATI about this issue.
