The i3 is above the Pentiums, but it doesn't beat a Phenom II x4 CPU by too much at stock (in fact, they can trade blows depending on the game and settings, although the i3 usually has a minor lead). Take overclocking into the equation and any Phenom II x4 can beat the i3s while being cheaper, although it would obviously have a fraction of the i3's power efficiency.
Even Llano is good at doing this because it is so cheap even for its performance and it can overclock pretty well, although it would probably be unable to top the i3s by much, if at all, but it should still be able to beat the Pentiums. Heck, I often see Phenom II x4s around for $100 or a little less and one with a half-decent motherboard could easily beat the Pentium G860 without much increase in price, if any at all.
Any motherboard with an AM3+ socket offers upgrading to Piledriver, Steamroller, and possibly its successor too. That'd be a good upgrade path.
