Dual-core or not, you're going to have marginal performance. The E-350 is akin to a souped up net book processor. While it works very well for what it does, it is only suitable for very light gaming. I think however, if you are willing to turn down graphics details and run at a conservative resolution, you may be able to get enough frames per second to at least get something playable going on. The other thing to realize is, Alpha games generally are very poor performers, and should not be taken as representative of the performance you'll see in a shipping title.
