That's silly to be honest. What are the chances you will get the CPU you want? Considering the ticket is not that expensive, and only a small fraction of the cost of the CPU, the odds of you getting a CPU is likely to be very low. This is gambling and likely for the person who came out with the idea to make money, more than selling CPUs.
With 1:30 ratio, you only need to invest 30 tickest ($300) to get (near) 100% chance to obtain $400-$600 worth of CPU, plus you can sell your remaining 29 unused CPUs in around $5-$10 each as a key chain. your total expenses only between $10-$155. Totally worth it to me.
What I mean is : unused CPU for you.
Because you only after the biggest prize, so others "used" CPU that you get from your ticket are unused for you, and you can convert them into key chain, and sell them for $5 - $10 each.
