If it looks like this is going to be delayed for a while, I would suggest waiting a bit, as I said before.  Nvidia 5xx cards incoming, AMD's 6xxx series going to replace the 5xxx series.  Plus next gen CPUs on Intel and AMD's side (Bulldozer is said to be AMD's biggest architectural overhaul in years) - if you plan on going Intel, you'll get the new socket (or cheaper i5/i7 prices).
