... You do know the CPU doesn't affect detail settings, right? You can put ultra settings with a Core i3. It's all about your graphics card. Your graphics card is dated, with many outperforming it these days. If you can, go with 4GB of RAM, and get a 1GB 7850 - big difference, higher detail settings can be set with your Core i3. Trust me when I say this, cores doesn't matter when it comes to gaming. It's all about single thread performance. Even if a game is optimized for multiple threads, it's not like you're gonna get horrible performance - you'll get good performance, just not as good as a Core i5 or Core i7.
