I have at present a HP 2010i computer with a Nvidia GeForce 9500 GT card in it, because my computer shuts down when I try to play train sim, I was told that I need to put a better card in like a ATI Radeon HD 4650 or4670 will putting a stronger card in damage my computer. It has a 11x2 215 processor 2.70GHz and the model is P6300uk AMD Athlon (TM)
