Is there a big difference between an i5 and an i7 processor? I'm someone who doesn't play games, but I do need a new laptop that enables me to keep multiple communication apps open 24/7, so I can talk to a variety of different sources. I don't want my laptop to slow down or miss a beat or have any delayed reactions. Would an i5 processor be good enough for my needs?
Also, what minimum RAM meets my needs? 4 or 8?
Finally, should I be concerned about GHz?
Mostly the apps I intend to keep open are Skype, What'sApp and maybe Zoom. But I need my machine to function with speed and efficiency.
