So i have an EVGA GTX 580 3gig and I have been contemplating buying a second monitor for my setup. I currently have a 22" 1680 x 1050 resolution LG monitor. The monitor i currently have would not be for displaying games, and would only be displaying programs such as chrome and ventrillo. The new monitor (http://www.newegg.com/Product/Produc...82E16824001482) which I am looking to purchase would serve as my primary display monitor for games and such, or browsing the internet when not gaming.
So here are the actual questions.
1. If I do decide to buy a larger resolution monitor, will that have a larger impact on performance of the video card other than just running at a larger resolution?
2. The card itself has 2 DVI inputs, so would I need a separate device to make this work, or could I just grab another DVI cable and plug it into the second DVI port on the card?
3. How big of an overall performance deficit am I going to be facing when playing a game like the Witcher 2 on max settings with ubersampling enabled?
I apologize for my ignorance.
