Because that's what BitTorrent is, and it's free.
I call bullshit. I regularly try to get older content on bit torrent, I have all but given up for a lot of stuff. While finding the torrent is easy, it is pot luck as to whether there are any seeders, the older the content the less likely to be a seeder. basically I find it at best a 50-50 chance of finding it, usually much lower for anything not mainstream.
If this is targeted at MOBA players, then it is probably overkill. I've got a 2011 Mac Pro with a Radeon 5870 (850Mhz GPU, 1GB VRAM). Playing League of Legends at 1920x1200, 60fps is no problem for this setup. These games are not graphically intensive, nor do they require much CPU horsepower. If you are going to drop money on hardware for MOBA gaming, spend it on a nice keyboard/mouse and the lowest latency ISP you can find. If your machine is less than 5 years old, whatever came stock is more than enough to play the game.
^this. it is not something you should buy as an upgrade, you should only get this sort of card if you are buying a new machine and that is your target gaming area. upgrading from a 650ti as the summary/article suggests to this would be brain dead moronic.
