The leadtek card has 4ns ram, which should clock above 500. Just look at mine @300/535, it's in the sig. I think the ones without TV-out are less than $100 now, while ones with TV-out are about $115. I know Skip was selling one in the classifieds that's hardly been used for $110 shipped (within continental US). The leadtek card needs ramsinks, but at least you know it has good thermal paste on 'em if you do it yourself. I just used cheapo radioshack sinks ($6) for mine. I'm sure it could do better with big ramsinks.
IMO these cards are neck and neck. The Gainward comes with cooling gear, the Leadtek with hardware-monitoring. Both have high quality 4ns ram.
