One problem with this sort of question is that if we allow them, we'll get thousands of them. There are tons of games and tons of computer configurations. We can't possibly host a question for each combination, much less answer them all, much less answer them all well.
The obvious solution is to make it more general; something like How can I check if my machine will be able to run a game?
Now you might think it's different since you don't have the computer, but not really. Can You Run It just compares the specs of your computer to the minimum/recommended specs for the game. You can easily do that yourself; look at the game page in Steam, or on the box, or just do a web search for the specs of the game.
If that's still not good enough and you're interested more in someone's experience running the game, you run into some other problems:
- We still probably won't have someone who's run the game with your exact hardware
- Your question will probably be useful only to you, or to a tiny number of people looking at the same hardware and game
- The question may also be too localized in time; in a year or so, it's unlikely that anyone will be buying the same hardware you are now
- Stack Exchange sites are a place for gathering expertise. Answering this question doesn't require any expertise; you only need to have the game and the hardware and to have seen how it runs.
SE isn't a good place for such localized questions, and people are likely to view it as uninteresting. Who wants to dig up the specs for someone else's game/computer? It's easy enough to learn how to estimate what the specs of a computer will let you do, so that's what I advise you to do.
