How do you know which graphics card is good & which is not? If it's not been reviewed anywhere how you going to know whether it's good or not? I mean, there are so many things in the graphics card like the core clock, memory clock, memory size, pixel pipelines, memory bus width etc.
What is the order of importance of all of them? Like would it be better to get a card with 128bit memory bus width with a 500Mhz core clock or one with 256bit memory bus width with 400Mhz core clock? I'm not looking to buy any graphics cards right now but just out of curiosity would like to know.
