Build Upgrade

So I've been thinking about upgrading my current build, mostly because my Q6600 @ Stock is running near 60 C on IDLE, and I'm using a pretty shitty motherboard coupled with old DDR2 RAM. The bolded text is the upgrades. My upgraded build will look like this:

  • CPU: AMD FX-6300 ~ $130
  • CPU Cooler: Cooler Master Hyper212+  ~$30
  • GPU: ASUS DIRECTCUII GTX560 TOP
  • Motherboard: ASRock 970Extreme3 ~$75
  • RAM: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600MHz ~ $60
  • PSU: Enermax NAXN 82+ 550W 80 Plus Bronze ~$55
  • Case: Antec NSK4480

Is this a reasonable upgrade or will the GTX 560 bottleneck the FX-6300? I am looking to overclock slightly on this build, the upgrade will cost about ~350 and I wanna stay in about that range. Any suggestions?

Every thing looks good it will be a nice upgrade.
