Hello I'm looking to buy a desktop in order to be able to work on OSX and play games too. I don't want a laptop for various reasons that I won't list here. On the second hand market, Macpro 4,1 are pretty cheap. I can buy one for 1,000$. After that, I just have to install a SSD, install more RAM and buy a graphical card... I think I could have a beast for 1500$. Is it worth it, processor/performance wise? Thanks a lot for your opinions, guys.
