Higher tank pressure does not equate to higher shot rates or faster ball speeds. The reason for this is that compressed air/nitro tanks are regulated at the nozzle. Typical paintball guns tend to run around 800 psi. Some people modify guns to run at lower pressures but the pressure is still regulated to a specific pressure at the nozzle of the tank or perhaps a reg attached to the gun itself. While a higher pressure feed into the firing chamber would imply a higher ball speed, it is not the case in practice and would present the challenge of dealing with balls breaking from the high pressure if you set such a pressure high enough. Not to mention the mechanical parts' ability to deal with more pressure than originally designed. CO2 tanks are unregulated because CO2 naturally regulates itself at about 800 psi. The big downside to CO2 is because its in liquid form, the temperature swings are rather large (especially if you shoot a lot). This can cause a pressure drop and erratic performance. Conversely, if one leaves their tank out in the hot sun, the pressure can become so high that the hammer can't hit the valve hard enough to open it and you get no shot.
As many mentioned, higher pressure tanks are indeed just for getting more shots per tank fill. 3000 psi would probably work for most players. Other than the inconvenience of going to get air more often, there isn't going to be much difference. And its unlikely you will run out of air in a single game. You'ld have to carry a large amount of paint with you to even come close. Most fields don't have 3000 psi fill stations as some also mentioned already, but many fields nowadays around me allow you to pay for unlimited air at the beginningh of the day. One of the fields I have been to around here also happens to be able to fill to 5000 psi.
As for choosing a tank, you can cheap out on the tank itself, but get a good regulator. The reg is generally the biggest expense anyways. Perhaps do some research on the reg as well. Not only do you want great performance (consistency), but reliability as well. Last time I went, I spent the day trying to fix my regulator as the o-ring broke. It was a rather simple problem, but it uses some odd sized o-ring that I could not find anywhere. Its still not fixed yet, and a call to the manufacturer can probably get me a new o-ring, but I've been lazy about it since I have to get the tank hydro'd anyways. My reg performs very well when working, but the reliability factor killed a day of paintballing. And thats not fun, especially since I rarely go anymore.
