Hi, i am trying to find a suitable upgrade for my work. i am working with usually render with FcpX (usually), Motions, Compressor, After Effects. Now, i read many many articles but i could not find a exact answer. My MacPro is mid 2012 6 cores 2.4gha, 48 gb RAM, Ati 5770 and a ssd. When i am workin with 1080p 1 hour videos -which is about 5-6 gb-, beachvalley effects occur on my mouse cursor. i could buy, 1. Second ATİ 5770 2. Ati 5870 or which graphic new generation graphic cards. i read that quadro 4000 does not work well -and so expensive for me-. As i read fcpX 10.1 colud work with dual 5770. But i don't know if the other softwares can use dual 5770 at a time. Thanks.
