I want to purchase the ATI card for my new macpro. Do I have to buy the upgrade kit from Apple? That card has a displayport and not 2 dvi......Plus the shipping is 5-7 weeks out. When I search newegg http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010380048%20106792627%201067940678&name=Radeon%20HD%204870&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-NA-_-NA-_-NA I'm unclear if any of these will work. Also, where is the best place to get more ram? Thanks.
