that is a lot for standard edition. Enterprise is meant to be able to handle more connections, but I have never tested the difference. how many simultaneous requests have you got it set to handle. average should be 10 per cpu/core but you will need to tweak to see what it can handle.
It also depends on your average page execution time too. lets say your pages all execute in 200ms on average, and your server can handle 20 simultaneous requests with 2 cpu's, that is 20 requests every 200ms so in 1 second that would be 200 requests, which you said is your daily average. So 750 requests per second would certainly result in some queuing and strain on the server. However 750 pages doesn't mean 750 cf requests unless they are ALL cf pages. I would suggest installing fusionReactor for some better insight on what is actually happening on your server and to monitor your page execution times, and find slow running pages and queries.
