I'm not a huge gamer and there is only one game that I want to be able to run on my desktop (Microsoft Flight Simulator X). I love aviation and this is really the only game that I want to run on my desktop. Here is my system: 1. Dell Dimension 1100 Series, Intel Cleron D Processor 325 (2.53GHz) and 256 cache 2. 512MB DDR SDRAM at 400MHz 3. Integrated Intel 3D AGP Graphics 4. 160GB Ultra ATA/100 Hard Drive (7200RPM) What do I need in order to have an enjoyable gaming experience with Microsoft Flight Simulator X? I want the game to run smoothly on my desktop with graphics that aren't distorted. Please inform me as to what I need for upgrades (Type of upgrade exact make and model, where I can purchase, and the price that I should pay) I don't want to spend a lot of money, enough to help me run this game and have an enjoyable time playing it without any hick-ups.
