I'm real close to buying a computer. For my budget i'll have the computer for a week or two running on an old crt or on a tv before i get an actual monitor. So before i invest money into a monitor what do i need to know about resolution? I'm working with a phenom 965 BE, radeon hd 6850, and a asus m5a78l-m lx plus. Recommendations are welcome, looking in the lower 100 range (100-150ish)
