My current PC is really giving me grief by being so slow. I am in dire need of a faster system but probably won’t buy for another month or 2. Here’s what I’m thinking: CPU: Intel Core i5-2500K Motherboard: something with an Intel H67 chipset Memory: 16GB DDR3 Storage: OCZ Vertex 3 120GB (or maybe …
