2008 Mac Pro: Any chance of upgrading hardware to current technology? Possible Duplicate:
  Can I upgrade my 2008 Mac Pro completely?  




I have a 2nd Gen 2008 Mac Pro 2.8ghz Quad Core with an 8800GT. I'm sure I can get away with the processing power and more RAM for now.

Is there any way possible I can put a modern day GPU inside this machine?

What does it entail to do such customizations? 

Could I gut this machine and upgrade it fully to current technology?

Thanks.
You should be good to upgrade to a modern GPU (PCI-X). Keep in mind that you will need to purchase an 'Apple' version of any graphics card you upgrade to.
