I don't think you will see a difference in performance between 110 and 220 volts, but your saw motor will be happier at 220 volts. A 1.75 hp motor is pushing the capacity of a regular 110 volt circuit, so nothing else can be on that circuit, and the chance for a voltage drop (very bad for the motor) when the motor is running full load (pushing the limits of the 20 amp residential circuit) is real. 220 volts means you are pulling half the current for the same power (your electric bill will be the same), and with lower current there is less voltage drop, less heat in the motor, etc. etc.
I am a horsepower addict. I admit it. I am now up to seven 5 hp motors in my shop, and I have NEVER regretted having too much power. I have had my 5 hp saw bind up/stop while ripping reaction wood. I certainly don't need 5 hp every day on a 10 inch blade, but there are times I use it.
I had a 3650 years ago. My brother-in-law copied my shop with a 3650, then for safety decided to go to SawStop - his family reminded him that as a doctor/surgeon they might be hungry if he cut his hand. He got one of their cabinet saws and spent the next couple years raving about how much better the SawStop was - he had liked the 3650 very much, but Saw Stop was that much better. So my long story is that you should consider their cabinet saw rather than the contractor saw, and as much HP as you can get (at least 3 hp, preferably 5 hp)
