Ok I decided to get a Intel Sandy Bridge Core i5 2500k and a LGA 1157 motherboard but I already bought RAM from newegg which is about 2 months old and the RAM only supports AM3 and Core i5 and i7 P55 chipset model motherboards. What do I do? I don't think I can get a refund and I don't feel like going through the hassle of refunding something that is fine. Can you guys recommend a P67 chipset motherboard that is ATX size modeled and has high quality intergrated sound cards, network cards, price ranges from $150-$250, is USB 3.0, 6.0gb/s sata ports, and is from a company with excellent customer service for the product.
