I'd get the rift S and see if you like it first. For me the valve Index is too much money to spend for the first VR and you don't even know if you'd like it plus the wait times for them are horrendous. By the time you get your hands on one the reverb 2 will be around the corner. I don't think you would be disappointed with the rift s and it would work great with your setup. You've got a few months to use it and have the option of selling it for the reverb 2 down the line if you want more.
