BleepingComputer.com: What Makes Some Parts Better Than Others

I have a loose understanding of cores in memory, hard drives, processors, and video cards, but I still would like a slightly more accurate description of what makes 'this video card better than this one', or what makes 'this RAM better than that RAM'? Can anyone help me out? To me, buying something that costs more for the same numbers seems like a waste of money. Can someone give me a paradigm shift on what to do with this extra cost?

While the core chip may be the same the supporting chipsets are different. Also the way the board is made, like are the componats soldered or glued on. You could have one card that has no heatsink and the other has a heatsink and fan.

Also brand name and where it's made are big factors. I don't know which are which, but I know for some people where it's made is an issue. And also what it's made of IE, gold parts or cheaper copper parts. 75% of the time, the more expensive item from the same brand is just made better. It might not necessarily effect the performance, but it will effect the durability of the item.

I've seen Intel's diagrams of the inner workings of a processor in physical realtime. I have NO understanding of that or why that matters. Does anyone know what goes on in there? I guess it really doesn't matter.
