Went to Micro Center a couple of weeks ago. At the PC Parts Department, where are all the mid-range GPU Cards? They only had in stock the ones around $100, and the ones $600+ I went home - my RX 470 4Gig goes for around $300? (Got mine around release Open-Box for $175) Mining? Like a specific card for playing Minecraft? I did try to do a search and found "discussion" at the Mac Pro Thread - didn't really understand what it is. Did a Google search - found videos - boring - reminded me of my Theoretical Computer Science lectures (snooze) and didn't really understand "Why".... since I'm a Gamer - do I even care? I feel sorry for someone who wants to build a decent budget priced Gaming PC... If anyone "in a nutshell" can explain or point me in the right direction. Thanks!
