Keeping the old ... young

[CyberGolem]

Hello,
So I own an Early 2009 MacPro that I'd like to keep going. It currently hosts a QuadroFX 4800 GPU, but I'm not sure how to get any more out of it. My problem is that it won't fully run my current monitor setup ::

• Apple 30" Cinema Display 2560 x 1600
• Samsung 34" Ultrawide 3440 x 1440

Surprisingly the Quadro handles both these monitors at their native resolutions, but there are issues with the Ultrawide. There's no problem with the Cinema Display at all (it has a traditional aspect ratio), but the new Ultrawide has blurry and aliased looking text. I've messed with a bunch of knobs and bobbins, changing the refresh rate to 30Hz makes the text legible but still unacceptable. So a few questions ::

1. Is there an update for the Quadro that I'm missing? I've been to the Nvidia site but everything I can make out says the card is up to date and has the latest blah-blah-blahs.
2. Will upgrading to a Sapphire 7950 or a GTX 980 work with my monitor configuration? I'm mostly interested in getting this new Ultrawide to play nice at its max refresh rate.

Lastly, I bootcamp Windows 10 for games and such, so I'm looking to have it work in both churches. Any help and/or constructive opinions are welcome.

Pretty sure the 980 can do much better than 7950 in most area, especially Win 10 gaming.

Sine you said that will be a "for Mac" 980, so I assume you mean that's flashed and no need to deal with the "black screen" issue.

However, if you need recovery partiton for any reason, be careful that you may not able to access it with the 980 in Sierra.

That or he means the 680.
