I'm waiting for gddr4 RAM supported motherboards to drop sometime next year before upgrading..currently using a 1366 i7 (ancient) on the x58 chipset (miserable). This will also get me away from the ****ty marvell sata controller i have on my current board.
It shouldn't be super expensive to upgrade since I'll only need a board/cpu/ram..might spring for a better case as my current one has horrible wire management options.
