It's the modders eternal question... Should I spend the afternoon overclocking the CPU, or do I need more RAM, or is my hard drive the real limiter? For gaming the formula is usually pretty straightforward: make sure you have enough RAM (usually not a factor), then it's all about the graphics card first and CPU second. I use PCMark alot, but I want to learn more from others. So: how would you determine what the best place to start upgrading performance is? For a twist let's assume that it isn't all about the graphics (so optimize around Office or "typical" use). Or just talk about your favorite Benmarking programs. (Incidentally I DON'T recommend PCMark despite using it. I'm kind of unhappy with it and it isn't free so I don't want others buying it because I mentioned it).
