Im building a desktop through Cyberpower desktops, putting an AMD Phenom II X4 925 Quad processor, ASUS M4A78L-M AMD 760G chipset DDR2 motherboard, 4GB PC6400 memory, 750 GB SATA-II 3 GB 7200rpm, and thinking about putting the ATI Radeon HD 5450 1 GB DDR2 video card. Dont need to play high demanding games on high settings but would like to be able to play them on mid settings. Any suggestions, or other computers?
