If my PC runs the game slowly I'll be upgrading it, because DBC will be a tipping point - there's a bunch of other games that could run a bit better, but none of them that I'd upgrade to improve.I've never heard of someone upgrading their PC for a specific game, that would be a crazy persons way of thinking, there's vastly better reasons to upgrade your PC. That being said, if it can run the CA Beta then you're fine to run the game, so again, I don't really understand what difference the spec information has to ones PC hardware, or lack thereof.
I wouldn't rely too much on the CA beta as a benchmark - you're comparing rendering one player and a background to 13 players, a stadium and more. You'll need to be running the CA full res at full speed to be sure of the game running well imo.
