Two issues: 1) SLI-support? Does SB Pro support SLI, so that you get a performance increase when adding a second graphics card? 2) The effects of high vs low screen resolution? Is the graphic elements designed to always be shown with the same number of pixels or at the same percentage of screen resolution? I think this is an important issue (very important for SB2) since it can have a great impact on the "battlefield performance". If the number of pixels used is constant then a higher resolution will result in a wider field of view and thereby increased situational awareness. At the same time all items will be smaller on the screen, so you'll need a larger screen to actually see what's there and read the texts. This rewards those that can afford a large monitor and a hefty graphics card to go with it in a way that's out of proportion. For the military users I don't think it's a problem since all users (within the class) can be assumed to have equivalent hardware, but for multiplayer in the civilian community it can make a huge difference. Better then to make sure that all users get the same amount of info (see the same amount of map/terrain) in any given view. At higher resolution it just looks "prettier", with small details visible at longer range and such and diagonal lines look less edgy. Cheers Olle
