Advice on my hardware choices for my first build.

[Bone Mosaic]

Hi, I'm a console gamer turned PC gamer and I'd like some advice from you guys as to whether or not my hardware choices would mesh well together. I've only been researching for the last week, so I wouldn't be surprised if my choices were a recipe for disaster!

Approximate Purchase Date: Most likely sometime early next year. Likely January or February. Or at least by the time I acquire all the parts and assemble them will be next year. I'm planning on buying the CPU and GPU last so I can get the best price for power at the time. And they're the most expensive parts so I'll leave them for last.

Budget Range: $1100-$1300 AUD. not including shipping. Although it doesn't really matter as it'll take a while to buy the parts anyway.

System Usage from Most to Least Important: Gaming, Net use, Movie use, everything else.

Are you buying a monitor: No

Do you need to buy OS: Yes.

Preferred Website(s) for Parts: http://www.pccasegear.com

Location: Australia

Parts Preferences: Intel CPU, that's it really, I have heard good things about Corsair parts so I'd like to use them where possible.

Overclocking: Yes, the GPU I'm looking at is factory overclocked. Not sure if that actually counts.

SLI or Crossfire: No.

Your Monitor Resolution: 1920 x 1080

Additional Comments: Would like it to just run smoothly and as cool as possible. I'm Going to buy an internal cooler after I build it. I'd love suggestions as to what would work best for me. Also i was going to go with an SSD but The loading speed doesn't bother that much, and the reason its going to take so long is I don't make that much money but I want to make sure I can build a quality system that will last a while.

I hope I wrote this up correctly. I look forward to and appreciate any advice.

Cheers!

Yup I missed the SLI or Crossfire part. Whoops
