interested in building a powerful 10.4.11 TIGER Intel HACKINTOSH? READ ON!!!!
AGP slot? or PCIE slot? regardless, lets dive into this and research what hardware we need.
for macos X we need to have the right GPU for the version of MACOSX..

(just pretend the mac mini isnt there lol)
remember the last patch for OSX TIGER came out on
November 14, 2007 for 10.4.11
The NVIDIA GeForce 7600 GT was officially supported in OS X 10.4.9 (March 13, 2007) and later, particularly for Intel-based Macs like the late-2006 24-inch iMac.
7600 GT Initial Support:
User reports indicate the card was working
with standard acceleration on 10.4.9 and 10.5 (Leopard).
Limitations: The GeForce 7600 GT, along with the 7300 GT,
was dropped in OS X Lion (10.7) because the drivers required 32-bit kernels.
that means you should have NO PROBLEM finding one for sale for a dcent price to use with a osx TIGER or LEOPARD hackintosh!
the 6600GT is also one of the most slept on GPU's imho..
works great for TIGER on INTEL! the 6800 agp's are not much better than the 6600GT's
the X1900 XT is one of the only cards that is compatible with all 4 OS versions,
between 10.4 Tiger + 10.8 mountain lion. but apparently it had overheating issues.
ive never had one so i wouldnt know.
