I'm sticking with Core 2 for a while. I managed to pick up a cheap QX9650, which performs brilliantly and was much cheaper than shelling out for the new board and RAM that i5/i7 would require. . Plus, my H2O 220 Compact won't fit i5 or i7 (the i7 boards with LGA775 mounting holes have awkward backplates that prevent proper fitting); so the additional expense of upgrading my WC kit has also been avoided. I think I'll wait for the next generation to come along, and maybe buy a new graphics card next year to keep things ticking over.
