Price is low, but so is CPU performance, in fact, it's slower than a 2006 Conroe in ST workloads (the CPU performance can challenge a Conroe @ 2.9 Ghz, but only in MT workloads). Sorry, but two faster cores are always better than 4 slower ones. You get what you pay for, I would avoid this.
Unless, you must use those newer instructions at a bargain price (e.g. you program a lot). I would not, however, exchange those for lower legacy code performance (SSE/SSE2/SSE3), which is about 90% of apps we still use today, and that's unlikely to change in the near future, partially because Intel doesn't make them as standard features for their lower end parts, and partially because not 100% of code can take advantage of them (e.g. you have to have good skills to begin with). Niche cases yes, world wide spread? Not yet. So no point to buy this low-end part in the first place today. Put money on deposit, and come back later (if it burns your pocket).
