As you can see, I choose to get a very expensive CPU as the base of the build, while putting in a very weak card. The reason for this is that this cheap card will easily game at your resolution, and GPUs are easily replaced. The same is not true of the CPU/mobo. So this gives you the best base to build off of with future upgrades. The mobo is high quality and future proof with USB3/SATA III support. The case is larger enough to fit any card and high quality so it can easily last many, many years. The PSU is overkill for the current build, but can handle whatever you throw at it as a single card. The reason I say "single card" is that you wouldn't want to stick another HD 4650 in Crossfire when you upgrade. You'd definitely want to grab a much newer card with the new monitor (like the HD 5850, 5870, 5970 or the upcoming nVidia cards). 650W would be more than enough to handle any of these, but would likely be a little weak for Crossfiring them (which would be a number of years down the road). By the time you'd be looking at adding the second card, you would either be looking at newer cards with newer features or would want a new PSU any way.
