My nephew has an R4. We received it with an Nvidia 680m and we also have his old ATI 6990m card.
From all of the posts I've read, the 680m is about equivalent to the 6990m, maybe slightly faster, but much more efficient.
It seems a lot quieter, but he complains that it's slower than his 6990m with Star Craft II. I've read on anandtech that it's supposed to be 20 fps faster than the 6990m on Starcraft.
I've noticed it doesn't perform nearly as well on Smite beta.
Is this about right or is there something else going on here? He wants to keep the 6990m and return the 680m. I think it's a bad idea to keep the older generation card. Any advice?

The 680m is MUCH faster than the 6990m. You are thinking of the 580m, which was roughly the same speed as the 6990m stock, but maybe 20%+ faster with an overclock. The 680m is probably coming up on twice as fast as the 6990m and is using newer and better technology.
If you don't want the 680m though, I can take it off your hands... -
make sure you have all of your settings on maximum performance and make sure you are not running on battery power. If that doesn't fix it then you'll be due for a driver upgrade.

I checked in device manager and he has the 680m. Unless the dell tech snuck in a lesser card and it's showing up as 680m.
I also tried the latest Nvidia beta drivers to see if things improved, but he says it didn't. -
OK, I fiddled with the global optimum performance setting in the beta driver and he says it's running fine now, at the same level as the 6990m. Much smoother on the 680m though.

The difference should be immediately noticeable compared to a 6990m as the 680m is much more powerful. Glad to know your happy now anyway

try whitelisting the games if he continues to have problems with different games. If you need help check out my sig.

Thanks for all the help. I will check the desktop notification. The games run much smoother on the 680m to my eyes.
680m vs 6990m
