Upgrading/Rebuilding a Gaming PC

Hello Tom's Hardware!

I built my current PC three and a half years ago. It's served me faithfully over the years but I think it might be time to upgrade. With the sales this holiday season and a recent promotion at work, I figure I might as well go overboard and rebuild one from the ground up, reusing only some peripherals. Back when I built my current rig, it was my first build and I didn't put too much thought into it. This time around I've done some thorough research, and have come up with a preliminary build.

CURRENT PC:
Case:
COOLER MASTER Centurion 534 RC-534-KKN2-GP Black Aluminum & Mesh bezel / SECC Chassis ATX Mid Tower Computer Case

Memory:

Planned PC:
Case:
Haven't made up my mind on this one. Maybe Cooler Master HAF 912?
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119233
PSU:
Not too sure about this one either. It's between the Corsair HX 750 for $139.99 or the Cooler Master Silent Pro Gold 800W for $99.99. Both after mail-in rebate. Or maybe the SeaSonic X750 Gold for $109.99.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087
Motherboard:
ASRock P67 Extreme4 Gen3
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157265
Picked this one because it was the only P67 board on Newegg with PCIe 3.0 support that I could find. I'm not doing any video editing so the Z68 seems pointless.
CPU:
Intel Core i5-2500K Sandy Bridge
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072
Out of stock currently on Newegg. Unfortunate.
Heatsink:
XIGMATEK Gaia SD1283 120mm CPU Cooler
http://www.newegg.com/Product/Product.aspx?Item=N82E16835233082
Picked this up for 5 bucks after MIR.
GPU:
MSI N560GTX-Ti Hawk 950 MHz core clock
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127578
Planning on going up to 2x560 Ti SLI at some point.
Memory:
G.SKILL Sniper 8GB DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428
Might get another 8GB as well. Not sure I'd need it though.
HDDs:
Keeping my current HDDs. But I will be getting a...
SSD:
OCZ Agility 3 120GB
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227726
Optical Drive:
Keeping the same thing here as well. I can't even remember the last time I put a DVD in that drive so it's mostly useless.

So I'm wondering if this is a good build. I'm aiming for a solid, balanced gaming rig that will last me another 3-4 years. I'd also like recommendations on a good case and power supply, that provide enough cooling and power to support a moderate OC as well as leave some room for future upgrades (at the very least a second GTX 560 Ti).

If anyone has any comments, advice, or wants to point out flaws in my build, I would be most grateful.

  1. PS: The total so far come out to be around $930, after shipping and rebates. I'd like to have this rig built by the end of the year, spending no more than $1000. I'd actually like to get it down to $800-850 if possible. Maybe going with a smaller SSD, cheaper mobo, and/or reusing my current case? Is PCIe 3.0 compatibility something to worry about if I'm not planning on jumping on the Ivy Bridge bandwagon for a few years?
  2. PS2: I'll be using this machine for mostly gaming, and watching some movies. I play on a 24" monitor at 1920x1080, with a secondary 21" running 1680x1050.
