Hello everyone,I`ve been checking and reading as many posts as I can here to get some info on wich graphics card I can use in my ancient 10 month old mac pro.I know all about the 8800 issue and that the 2600 will work.Iam wondering what all my options are such as what cards I could flash or what cards I can use on the windows side and wich ones on the mac side.I read that the 2600 can be used with crossfire under windows but is that the windows version of the card.I have read a ton on here but there is so much conflicting issues that I would like to know what I can do to upgrade my 7300 gt.Thanks for any information you have.
