I've recently purchased a Mac Pro 1.1, one of the Xeon 64-bit workstations. First Macintosh I've personally owned and it's a beauty.
I'm already planning on boosting the processors from the Intel Xeon 2.66Ghz dual cores to the 3Ghz quad core counterparts.
I'm having some trouble finding a suitable graphics card though, the information I've found online is pretty convoluted. Can anyone suggest a graphics upgrade that would speed up 3D rendering in programs such as After Effects and MaxMSP please?
Currently running 2x NVIDIA GeForce 7300 GT 256mb

G'day and welcome to the forums felix.

The 7300GT's were a beast of a card with a high failure rate. Best I found in Mac Pro days was either a flashed ATI Radeon HD4870 with 1GB memory or the later 5700/5800 series. Not too cheap though.

The best CPU upgrade for your Mac Pro is the Bloomfield 5500 series 2.66GHz. If you Google replace Mac Pro CPU's you will find directions at sites such as MacRumours. Do not worry about the original 3GHz CPU's as the upgrade is not noticeable.

Sufficient memory is next, suggest with what you want to do 12/16GB, and an SSD will be the biggest bang for your buck.

Remember whilst your Mac Pro may be 64bit, the EFI is 32 bit, so Lion OS X.7 is the final operating system you can install natively with making your Mac Pro a Hackintosh.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Thanks for the advice!

Yeah I've noticed that, even if I have it running with the 64bit kernel extensions it still doesn't want to update
Would a processor upgrade (a drastic one) change that?

No. Like Harry said, Lion is as far as you can upgrade to (10.7.5).
