I have a PC with 1GB RAM, AMD64 3000+, X800XL. I use it mainly to play games. But new games like Company of Heroes, Gothic 3 , etc make my PC to use medium or low settings to play without lagging. I design to increase the memory from 1 to 4GB and to buy a new graphics card like X1600 or 7600. Am I going to see a real difference in performance, about 50%?
