  1. If you dual link video cards say 256mb and 256mb will they combine and equal 512mb? If they don't then then whats the point of dual linking video cards?

    Well they could render different parts...Like one part render background and another can render the gunshots and main stuff....Thats just what i think though =] Just take off stress off of each videocard

    So they don't literally combine, but in some ways it acts like they do by taking some stress off each card so they don't have use so much mb to run a game and etc... is that right? Also would it better to buy two cheap video cards like say 200 dollars together and link them or just one expensive one for like 370 dollars?

    You get the benefit of a large framebuffer in an SLI\Crossfire which helps when you're running at extremely high resolutions such as 1600x1200 and beyond. IMO, dual-GPU systems are good only if you have a large monitor and want to game at aforementioned resolutions. Otherwise, the extra power consumption and heat output would have you spend as much as (or even more than) a single, more powerful card on good cooling and a good PSU. What's more, dual-GPU setups don't even offer 2x the performance of a single card, so the performance benefit is not what you'd (theoretically) expect it to be.
