Big Iron: On Display - Video card basics

As gamers, unless you're a Minesweeper junkie with an epic Peggle jones and no further aspirations, you're going to have to have a dedicated video card in your rig to get any kind of decent graphic performance.
Wait, what?
The short answer for why that's the case is: "Math is hard; let's go shopping." However, it's not us saying that, it's the CPU.
I know what you're thinking. "BI, the central processing unit... all it does is math!" Or perhaps, "You cheap bastard, you still owe me five bucks for your share of the beer last week." You're right, of course (about the CPU, anyway...). In terms of raw computational horsepower, a modern processor is a potent customer. However, of necessity, it's also a generalist.
In order to obtain truly prodigious performance, we need to bring in a specialist. That specialist is your video card. Think of it like this -- an Olympic decathlon competitor is in phenomenally good shape, and a world-class performer in ten different events, but in any single one of those, their lunch will be summarily eaten by someone who makes that their sole pursuit.
