Now I understand the new terminology. C3 cam series refers to smaller cams. C4 series refer to larger cams. For example a C3, #3 is the large hand/fist size, 3 inches wide.
Black Diamond C3 Camalots have three lobes, while C4s have four lobes. That is the main difference and the reason for the naming convention, although C3s do generally cover smaller sizes and C4s cover larger sizes.

The OP seemed to be budget minded so I wouldn't recommend buying doubles right off the bat, unless one is climbing at Indian Creek. The money would be better spent rounding out the rack and stocking up on sewn slings and carabiners. The four largest hexes cover the hand sizes and are lighter and cheaper. Personally, other than big walls and other aid climbs, I've rarely carried doubles in cams, even on long, multipitch climbs up to 5.11.
Outer Space, a 5.9 crack route, features a 300' perfect hand crack. I remember climbing it on one occasion, thinking I needed to conserve my #1 and #2 Camalots since the crack was that size. I used nuts and hexes and slung chicken heads. When I got to Library Ledge which bisects the crack into two perfect pitches, I realized I had not placed my cams at all.
