Hi All I recently bought a Mac Pro on eBay, one without CPU, RAM or GPU. http://support.apple.com/kb/SP30 This is what I get when the serial is inputted into Apple support site. I have added 2 E5345s Xeons and 4x2GB PC2-5300 FB RAM and a X1900 XT, the Mac boots into windows all fine. After research my edition of the GPU cant be flashed to work (256MB). The support site doesn't list the 8800GT/GTS, is it not compatible? or just not available at time of purchase? I have listed the two I have seen on eBay below. Will they work? Also how to tell if my Mac Pro is a 1,1 or a 2,1? http://cgi.ebay.co.uk/Mac-Pro-Nvidi...ing_Apple_Mac_Accessories&hash=item53e82ea75e http://cgi.ebay.co.uk/Apple-Mac-Pro...ing_Apple_Mac_Accessories&hash=item53e82f3dee thanks for all help in advance.
