Hi guys, A friend of mine is about to buy a second hand Mac Pro and he has some questions. The hardware: 2x Dual-Core Intel Xeon 2 GHz; 1x NVIDIA GeForce 8800 GT; 250 Gig. HD (WDC from Apple); 2x 500 Gig. HD Samsung 8 Gig (2x2GB; 2x1GB; 4x 512 MB) 667MHz DDR2 FB-DIMM; 2x SONY DVD RW DW-D150A; Airport Extreme (802.11 a/b/g/n); Apple Mouse; Apple Aluminium keyboard Software: Snow Leopard en iLife 09. Is this setup worth €900? If not, how much do you think? Is it possible to put a new processor and graphics card in the Mac Pro's? He has a ati 5870 PC version, can he use this in the Mac Pro? Thank you!
