Hello. I have a custom built PC with an Intel DH55TC Motherboard and an Intel Core I3 Processor (1st generation.) It is a little underpowered with this configuration, so I was looking to upgrade the processor. Is it even possible to upgrade the processor in the first place? If so, would I be able to put one of the new Intel "Sandy Bridge" processors (such as this one: http://www.amazon.com/Intel-i5-2500K-Quad-Core-Processo...) in my motherboard even though the motherboard came out before Sandy Bridge? Any input is greatly appreciated. Thanks.
