In addition to it being difficult to predict what a high school will be like in 5-6 years, many of the schools highlighted in US News are magnets, charters and exam schools. Even if you move to the area, there is no guarantee that you will get into those schools. For example, I live in the Denver area. The only "gold medal" US News school is Peak to Peak charter. It is a lottery based K-12 school in the Boulder Valley school district and very difficult to get into.
Aside from the lottery issue, it is difficult to know what type of high school would be most appropriate when your child is so young. Our local high school is a US News silver medal school, IB school and extremely overcrowded. For my high achieving DD12, it may be an appropriate choice. For my highly creative, HG dysgraphic DD9, it probably would be a disaster. There is a very good chance that my kids will go to two different high schools.
At the elementary level, there are many different options in the Denver metro area -- gifted charters, gt center programs (school within a school), etc. Which one would be most appropriate? It depends upon your kid. Many cater to high achieving gt kids. Some only accelerate one year -- period. Some use block scheduling to allow movement between grades. I know of one that bills itself as highly individualized so better for PG and 2e. Once again, a lot of these schools are a lottery and/or have testing requirements.
There is one school district, Adams 50, in the northern part of the metro area that has eliminated age-based grouping/grades and instead groups according to ability. It might be worth a look if you are considering the area anyway. It has garnered a lot of attention in the local press but I don't have any personal experience with it or the immediate area.
I agree with polarbear, you should look for a place that you would like to live and then try to figure out the school options available.
