SAPPHIRE HD4870 or XFX 9800 GTX ?
 

My bro's box wanna Graphic update, after my research, it seems that HD 4870 (http://www.sapphiretech.com/us/produ...gpid=245&grp=3) is more powerful as it goes with the newest Mac Pro, but 9800 GTX (http://www.xfxforce.com/en-us/Produc...spx?lang=en-us) seems more stable and the drivers for OS X is better, so can someone here tell me which one is more friendly or issueless with Leopard ?

Or can someone recommend the most powerful Graphic that is fully compactible with OS x86?

Thanks in advance!!


My Bro's Box:

AMD 3600+ socket:AM2
NForce 5 Chip Mobo
1Gb*2 DDR II 667Mhz
Audio ALC 888

I can only tell u about the Nvidia, and they work great with an EFI string. Simple, plain, no Problems.
