GPU or CPU upgrade???

[Impaler4]

Ok so i'm well into gaming and pretty much nothing else. Atm I run an oc'd Q6600 @ 3.4 Ghz 4gig 9800gx2 and was wondering what to do now.....

Either upgrade my mobo etc like the link below

or

Get a 480/495 GTX and add it to my existing rig.

What's your thoughts guys as everyone I ask says something different and it's doing nut in.

i usually play at 1680x1050, ocasionally play on 50" TV at the same res (mainly for my boy to play need for speed shift).

I didnt relise nvidia are that far behind on the release date thought it was ment to be end of march.

What i dont want is to play any new game below max settings, so GPU the MOST important thing?

Won't I be in danger of bottlenecking it if I get the 59xx/480gtx??
