i'm in the same boat as you. my mobo died in the summer and i have the same CPU. i couldn't find anything decent that was new or even allowed me to overclock. on ebay all i could find were cheap gigabyte mobos from china and any good used mobos i found were going for the same price as a whole computer upgrade. the most cost effective thing to do may be to get a a 4th gen I5 CPU and mobo that you will be able to reuse your ram with
