I am overclocking my Q9450 with air to about 3.4 ghz or so. Any suggestion on RAM? If I get a 1160 mhz ram it seems I will have to downclock it compared to an 800 mhz?

Hands down. The 1st one is way overpriced, yet the fastest of the 3. Your target is 3.4Ghz so 3400 / 8 = 425Mhz FSB x 2 = 850Mhz DDR2 is what you need to get there. The XP6400 may be able to run at 850mhz, but for the same price, why not get a faster kit?
Are you sure about those prices? It's funny to see DDR2-800 at the same price of DDR2-1000. If that's the case, buy Redline DDR2-1000 any way.
If prices differ and you really intend to go that far, around 3.4Ghz, then you'll need something above DDR2-800. The redline DDR2-1000 should do fine.
If you plan to get only 20% oc, DDR2-800 is what you need.
