Two monitors and video card memory capacity

[Jovaras]

Hello,

I'm looking forward to purchasing GTX 770.
If I purchase a second monitor with it as well, and one will be used for gaming and another just for browsing internet at the same time, do I need to purchase GTX 770 4 GB variant, or I'll be just fine with 2 GB? Or higher memory capacity is only needed when I extend the gaming screen across the both screens (I'm not going to do this)?

The monitor I have atm is 1920x1080, I'll probably purchase same resolution monitor.

Thanks.

I'm driving 3x 24" 1920x1200 monitors off a GTX 760. You don't have anything to worry about there. The extra memory never hurts to give yourself some overhead where gaming is concerned for the future, but it's not a necessary thing just for multi-monitor.

thanks, but do you extend the game screen across these three monitors? Or just use them for displaying desktop/internet things?

I was able to run borderlands 2 in NVIDIA surround across all 3 with no issues. I wouldn't plan on surround gaming with just 2 monitors as it puts the "center" of everything square on the bezels. You need 3 screens. It didn't sound like you were planning on that from your initial description though.

1920x1080 * 24 bits = 49766400 bits = 6220800 bytes = 5.9 megabytes

Even with triple buffering, as I understand it, that comes out to only 18 megabytes frame buffer for a whole screen
