stupid question but is on board 4K better than 2 ancient Nvidia 9800gt cards

[Greg Johnston]

Looking for answer to a rather stupid question but sometimes we can be surprised, I have a new gigabyte motherboard with supposed 4K graphics and 2 ancient gigabyte 9800GT cards, I'm sure that the on board 4K is better, can you surprise me?

What board is it and what cpu are you using with it? On second thought not that it matters because the 9800gt can't display 4k, it's max res is 2560x1600. http://www.geforce.com/hardware/desktop-gpus/geforce-9800gt/specifications
