Hi, I am planning to build a new computer within the next year. I have already bought an AMD Athlon II X3 455, but I don't know which kind of motherboard I should get. I don't think I will upgrade this computer very soon after I get it, maybe a year for a graphics card, and even 3 to 4 years until a new CPU, if I end up needing more cores or more "horsepower" . I've heard that AM3+ is coming to a close in about a year and a half. Still, is having the luxury of compatibility for things like SLI and AM3+ worth the extra money, for the slim chance that I do want to upgrade? (I'm "very young", so I only get about $15 a week by mowing lawns.) Thanks if you replied!
