POS Consequences on mining ?

I am new into Ethereum and ether. I am currently considering investing to make a 6 GPU rig to mine ether. Based on my location, the cost of the hardware and the current ether rate, using different only calculator simulator I find out the return on investment would be around 2 months.
Nevertheless , I read that Ethereum is going to turn into Proof Of Stake instead of Proof Of Work. I didn't fully understand yet what are the differences between both, but it seems that this change may make the mining obsolete or impossible for miner ???
Hence, I am wondering if I should really invest in this hardware taking the risk to get it being useless in few months ?
Anybody can commen, highlight or clarify about this point ?
