I read the entire thing and I think it is cool that now days this is possible. However, I got to thinking at $.50+ per hour, if I play 6 hours a night, that's $3.00 a day on weeknights. If I only play $8 on weekends it adds up to $23 per week. This would equate to $1196 per year at (23*52). Basically I'd much rather invest in a gaming rig. My CPU and GPU haven't required upgrades now for years in this day in age. At least if I invest in a gaming rig I actually have a gaming rig.
While I respect and find the technology fascinating and cool, it feels like leasing a car I'll never own versus owning and evening buying a new one every few years at a much lower price. For those who game a few hours a week however, I can see this being a cheap alternative to a gaming rig.
