Depends on the price of the upgrade, is it diy or you having the upgrade done? If you're using sidehack's kit at .2, the return on investment just for the upgrade would be within the first few weeks if not days ( base on just 1 blade at current difficuly factoring in an increase of 117% per month), and would continue to earn positive revenue until July. Plus if you decided to sell them you'd be able to easily get more in return. So is it worth it? I think so. Problem is if you're using the backplane and the 1000watt psu, you'd have to find a 1500 watt psu.

Thanks for the good detail description, it would be using the sidehack upgrade service I also need to send them and get them send back which will also cost a fair bit. The PSU the now is the 1000w and seems to be running at max capacity and I cant seem to find one that fits for 1500w.
Hopefully the rig can go to a good home or be added to a current rig.
Cheers for all the advice
