Forgive me if this is a stupid question.... I have a Dual 2 GHz PowerPC G5 mac at my work which i use mostly for graphic design ie. Creative Suite 3. My employers have just bought me a G5 mac off ebay for me to use at home but i fear it's never going to be fast enough to open 500+mb files in a short time because it only has a 1 1.6 GHz PowerPc Processor. I am not very technically savvy when it comes to macs so i'm not sure if it's possible but can i add a new processor to it to make it a dual processor? When i open the side of the unit it has one processor with the G5 logo on it but looks like there is room underneath it for another one. Thanks.
