Larry, obviously your lowest gear will be significantly higher. A 34/27 will be about 13 percent taller than your present 30/27 low gear. Only you can tell if that's important or not.
The other main difference will be giving up some middle range if you are one of those guys who likes to ride with a fairly straight chain line. With your triple the 39T middle ring offers mid-range gearing that's hard to duplicate with a compact unless the chain is crossed to a greater degree.
