What do you look for in a good video card?

What specs, specifically. Yes, I know the amount of RAM it has, but what else? What determines, for example, one 512mb card from another 512mb card?|||Yea, benchmarks is really the only sensible way to go. I use passmark.com . The name of the product also says a lot once you get to know video cards.|||I could help you decide, email me if you want, tell me what you need a video card for and Ill let you know what a good card would be, also do you have a preference on what company the gpu is made by? (either Nvidia or ATI) I know more about Nvidia cards|||Actually, I really don't care about the amount of RAM it has. The RAM amount is VERY misleading. The only real way to compare video cards is with benchmarks.|||Go to a site that does benchmark tests and compare them there, that's the easiest way to tell which is better.
