Im trying to open a file that's 17920 X 17280 on my imac in preview. When ever I view this it takes a little bit to render and than when I got to rotate the program crashes. I also tried using phase one media pro and it freezes up when I try to load this. What is the recomended ammount of ram i should have on hear. I'm running it on a core i3 processor and the file is 1.8GB

I have a PC desktop too but older than the mac. I've been using PC since 1998, even used Windows 3.1. Switched to mac in 2005. Still run windows on bootcamp and use windows 7 for minecraft and everything else. I probabley use 50% Windows, 50% Mac. Want to build my own PC next year when I save up. I am well aware on everything I want to have such as a G-Force GTX 680, two running SLI. Two 8 core intel xeons for processors, 16 GB of ram. A capture card too, thinking of water cooling it also. Mac Pro are great but way too expensive. Macs are just so beitiful espicially there Macbook ZPro's that can run 2 graphics cards now and. If only imac's were upgradeable well anything's possible. Who you calling an apple fan boy? :D Well I am a fan, of thier iphone's ipad's and there software. I could always Hackintosh a windows machine to be able to duel boot apple OS. Cheers!
