What would be the most cost effective (in terms of priceerformance) way to upgrade this system? Looking for higher frame rates in MS Flight Simulator. My intuition tells me that upgrading the graphics card is the best way to get the performance that I want, but I have read that 3D rendering also puts a huge load on the CPU. Thinking about replacing the 4200+ with either a 6000+ or an FX-64.
