It's worth a google to see if their are people with the same CPU as you able to play it. It might be old, but an i7 is still a decent processor. You'll only run into issues if the game requires instructions that the first gen i7's don't support, but since the minimum spec's for the game are a first gen i5 (recommended is a 4th gen core-I, not minimum as you say) I think you'll be fine. A quick google suggested there are people playing on an i7-920 (lowest spec'ed gen-1 i7).
