I can't believe I was going to waste more money on more video cards
The little guy can't compete with all the farms out there these days anyway
What's the point of wasting video card life for chump change
Sorry about your card. You have to understand that there is risk in any business (yes you're trying to make some money, we can call it business). Here's one example: You'll buy a car to drive for Uber and somebody will still it or crash it... You can do two things, start over or not at all.
One day you'll look back and will be happy (or sad) about the decision you're making right now.
