For a while now, I've been looking to put together a low-to-mid tier gaming PC to upgrade from my five-year-old laptop. My main goal is primarily to be able to run Team Fortress 2 at maximum settings for the next several years (and since the game is continually being updated with more and more complex graphical features, that isn't as static as it could be). A friend of mine recently put together a computer of his own with some help from the imageboard-based "Logical Increments PC Buying Guide", which I've been using as a basis to work with until now. But there's one complication: Said friend also purchased an AMD Phenom II X4 940 that wasn't used in his PC build due to the AMD2+ socket it used being incompatible with the motherboard he bought. Since abandoning it would be a waste, he sent it to me... and I've had trouble finding information about how to make use of it in the little time I spent researching since; AMD2+ motherboards seem to be relatively difficult to get at this point. And even if they are, I'm not sure whether it would be worthwhile; I do want to be low-budget about this, but if an AMD2+ motherboard would become incompatible quickly, then it might not be worth the free CPU and maybe-clearance motherboard/RAM/etc.
So, the short version: I have an AMD2+-socket CPU, and I want to know whether it's worth using for building a low-mid gaming PC, and what sort of motherboard would be needed if I do use it... and where to get it.
Hopefully I'll think to stop back in on this topic soon.
