I know that there are topics on what's the best videocard period. Most people seem to prefer Radeon. But what's the best videocard for a lower-end system like my Athlon 600. I haven't seen this posted before, though I have heard that the V5 doesn't scale well. Also, is it true that Nvidia's relatively poor image quality can be solved through proper calibration? I saw one person say this once, and noone commented.
