New gaming build ~ $900 AU

I'm after some advice/opinions on a new gaming build. I've given the details of what I want, and the parts I have currently chosen.
Just wondering where I could improve and/or save some money.

Approximate Purchase Date: 3-4 weeks

Budget Range: $850-900 AU

System Usage from Most to Least Important: gaming, movies, AutoCAD (and similar)

Parts Not Required: keyboard, mouse, speakers, monitor (1x 1920x1080 (primary use), 1x 1680x1050), OS (Win7 Home Premium 32bit)

Preferred Website(s) for Parts:,

Country of Origin: Australia

Parts Preferences: none (though current build has Asus mobo and GPU, hence the selection below)

Overclocking: Highly unlikely (dont know enough)

SLI or Crossfire: maybe

Monitor Resolution: 1x 1920x1080 (primary use), 1x 1680x1050

Harddrive: Seagate Barracuda 7200 (1x 750GB, 1x 1TB) keeping these, if possible, so I don't need to reinstall OS and other programs.

Additional Comments: Initially was just going to upgrade GPU, decided to do complete new build. It will be my first build. Sorry for the long post.

Parts currently looking at (~$850AU):
Antec Three Hundred Case -
Intel CPU Core i5-2500K - LGA 1155 -
ASUS GTX 560 Ti DirectCU II Overclocked 1GB -
Corsair TX-650 V2 Power Supply -
Corsair 4GB Vengeance DDR3 1600MHz CL9 (CMZ4GX3M1A1600C9B) -
Asus P8P67-LE v3 Intel Mainboard (B3 Stepping) - LGA 1155 -

  1. Hello ZanderW;

    Your motherboard choice is not ideal for a possible SLI setup. You'd want to be able to run SLI @ x8 x8 and not the X16 x4 option the Asus P8P67-LE allows.
    1 x PCIe 2.0 x16 (blue, single at x16 mode)
    1 x PCIe 2.0 x16 (black, at x4 mode, compatible with PCI Express x1 and x4 devices)

    Gigabyte GA-Z68MA-D2H $143 will run SLI graphics cards at x8/x8.

    No aftermarket CPU cooler in your list yet. You can easily learn to overclock and it's easier to install the better cooling now than later on.
    CM Hyper 212+ $32
  2. A 650w psu would be a bit of an overkill for a single 560ti, you could try for this
    so you can up the ram to 8gigs
    And btw, a 650w psu won't be enough for dual 560ti's in SLI
  3. Bump your PSU up 50W, it's not necessary, but as a general rule of thumb, overkill, it can't hurt.

    WR2 is right on everything he has said, I truly do suggest that if you're buying an i5 2500k, you overclock, otherwise, downgrade your card to save money.

    Why would you bump up 50 watts on the psu if 650 watts is already an overkill? even a good 500w psu can run that system fine.
  5. Hey, thanks for the input.

    @WR2 - I've taken on board what you've said and changed to the Gigabyte GA-Z68MA motherboard, and also added the CPU cooler to my list.

    As for the PSU, if 650W is not enough for dul 560ti's in SLI, I take it a larger PSU would be necessary to keep that option open? Any recommendations?

    As for the RAM, how does the one I chose compare to similarly priced options. I only need 4GB because of my 32 bit OS.

    On to the case, will all the selected parts fit alright, or are there any other options?

    Thanks again.
  6. I really reccomend changing the MOBO to
    Its probably one of the best Mobo's at that price.

    Also for the Corsair TX650 v2, its only got 2 6+2pin PCI-E connectors. You'll need 4 of them for dual 560ti SLI setup.
    To be on the safe side, you should up the Power supply to either:

    If you are getting a CPU cooler, try getting this
  7. I'm OK with the amount of power the TX650 V2 can supply. It can handle an average OC for the i5-2500K and 2x GTX 560 Ti in SLI.
  8. @ ASUS GeForce GTX 560 Ti DirectCU II TOP Review and SLI Performance

    I'm guessing your system with a CPU OC would need a bit less power than the test system used @ hardwareheaven.

    This is an Australia forum, people over here will have a better knowledge of where and what to buy in Australia

    Not sure its a great idea suggesting other forums ;)
