Oh yes, its that time of the century again

Yeah, i kinda need some advice about upgrading.
My current specs are
Motherboard: P5Q-Pro
CPU: Intel Core 2 Duo E8400@3GH'z
Graphics: a GTX 260
RAM: 4GB

I really dont think the proccessor is shit though, its still costs around 225$ (130ish quid)in iceland, but its only a dual core, the motherboard and ram are fine i suppose, but graphics card i suppose is the only thing thats getting outdatedish (even though its the newest item in my pc)

Anyway on to my thoughts, since money is limited and i dont want to spend around crazy amounts, i was either thinking of getting the new Phenom X6 hexcore, some nice cheapish am3 motherboard and 4gb ddr3, but this leaves out the graphics card and i simply dont really have money for much more so should i either get the GTX470 and possibly try to fit in a quadcore intel proccessor that is about the same value as my current proccessor?
