I am going to buy one of these three video cards from eBay. I know NOTHING about flashing and don't want to do it. I am happy to buy the card from someone on eBay. 5870 ($320) http://cgi.ebay.com/Mac-ATI-5870-1-...eo_TV_Cards&hash=item35af9543d6#ht_2591wt_963 5770 ($209) http://cgi.ebay.com/New-Mac-Pro-ATI...eo_TV_Cards&hash=item1e5f686903#ht_3123wt_963 5770 single slot (more quiet video card) ($219) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=130446904745#ht_2959wt_963 Based on these three, which one would you recommend for me? I'm looking at the these three main things in the card, in order: 1) Graphics power 2) Price 3) Ease of installing card 4) Quiet card These are just my guidelines. If you have a personal recommendation out of these three, I would be greatly appreciative to hear what you would recommend. I have a late 2006 Mac Pro. Many thanks.
