Hello, first of all im new to mac hardware and i have some questions: I have a Mac Pro 1,1 (2006) Model Name: Mac Pro Model Identifier: MacPro1,1 Processor Name: Dual-Core Intel Xeon Processor Speed: 2,66 GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 1 GB Bus Speed: 1,33 GHz First Question was if i can install any other video card (i can get a 8800 GT fast but for pc) but it seems that i have to buy one for mac. The RAM, i want to upgrade the ram. I Found on ebay some FB-DIMM for mac, but can i put 2 x 4 GB in it? it's not to much? i mean can i install 32 GB of ram in this mac? or only 16 GB? Thanks!
