So I sold my 2006 Mac Pro, which had 12 gigs of ram, OCZ SSD and ATI 5770. (From Apple) I picked up a 2009 Mac Pro, the quad 2.66 model. Threw in 16 gigs of ram, the same SSD, but now I'm stuck on two things: 1.) WiFi: It has bluetooth but no wifi. I have an airport express so I can just hook up an ethernet cable to it from the express, so do I even need a wireless card? Would the wireless card give me a better connection or is the ethernet cable/express good? 2.) I have an nVidia 8800GT in it. I obviously want to upgrade it, and have read the thread on Mac Pro GPU's. Basically, can someone summarize it for me based on what I want: plug and play Apple compliance with as much power/bang for the buck I can get. i.e 5870 Apple card is good, but expensive and a bit outdated - if I can find a card that requires little user tinkering and works great, let me know! What are the top cards in this regard?
