Upgrade help....if at all....

If you're building a new machine in 6 months, why throw money away upgrading the current one? If it was me, I'd probably save my money for the new machine.

What you do, though, could depend on how much you want to spend, and what you want to build on your new machine.

If you want to go intel, you could get a Core2 E6300 (~$190) and the ASRock DUAL-VSTA mobo (~$60). It's not a great board, certainly not a good overclocker, but I've heard it works, and will let you use all your old ATA drives, your current DDR RAM, and your graphics card.

This is pretty much the cheapest way to get into a Core2, and, since it's still a good, recent CPU, you could use it when you build your new machine, and only hace to throw out the ASRock mobo. With a good mobo, good RAM, and decent CPU cooler, you could OC the 6300 to very nice speeds.
