So i have the above listed graphics card in my 2008 mac pro 8core with 6GB of ram. I am wondering a few things A. I have dual monitors and one of them does not look as nice and the same colors as the opposite. They booth are on the same settings and same color profile. So i am wondering if the monitor is bad or the graphics card possibly? B. If i wanted to upgrade and not spend a ton of cash what would you recommend. My screen are capable HDMI and i have 2 so please keep that in mind. Thank you so much.
