[Solved] 1st Build. Gaming <$1000

Hello. I hope you are all doing well. This is my first homebuilt gaming PC. I filled out the form:

---------------------------------
Approximate Purchase Date: This week or early next week

Budget Range: <$1000. Hoping to get the best value for money and appropriate to my needs.

System Usage from Most to Least Important: Gaming, Watching Movies

Parts Not Required: Monitor, Mouse

Preferred Website(s) for Parts: no particular preference. I heard that newegg is a good website.

Country of Origin: Canada

Parts Preferences: No particular preference, but would like a nice upgrade path.

Overclocking: Maybe, if it is safe and not too difficult.

SLI or Crossfire: Not sure if I need it.

Monitor Resolution: 1920 x 1080 (i have a HDTV 1080p and would like to make full use of it)

Additional Comments: Would like to get the best value for money and keep under $1000 (approximately). I enjoy MMOs, and some FPS (crysis 2).

Thoughts? Suggestions?
I have a few specific questions. Will everything fit and be compatible with each other?
To play with mid-max settings in a single 1920 x 1080 monitor, are these parts overkill or sufficient?
Will I ever need SLI/Crossfire if I only plan to use 1 monitor?
Is it a better idea to spend say $500 that'll last me a couple of years, or say $1000 that'll last me 4-5 years? Initially, I had only planned to spend a little over $500 for a budget gaming build, but after reading around and finding out how much I can get for just a little more ... whoa... suddenly I'm at $1000

Thanks in advance for the help. Looking forward to hearing all of you experts' replies.

Thats a solid build. I would maybe make the jump to the HX750W PSU for the modular cable system. Its nice to leave out cables you are not going to use. Still, the TX is a great PSU. I had a P8P67-M Pro (pre-B3) and it was great. I RMA'd it for the Sabertooth just because I wanted a physically bigger board (and, geez, the Sabertooth has thermal armor!!!)....
