ok today i went around my local computer shops (in Australia, so no newegg)

and here is the deals they gave me


Shop 1

Intel Core i5-750

COOLER MASTER Hyper 212 Plus
http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065&Tpk=coolermaster%20hyper%20212%2b

CORSAIR CMPSU-750HX 750W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010&Tpk=corsair%20hx750

4 GB kit (2x2GB) DDR3 1600 G.skill Ripjaws

All this costs $1450 AUD here

Shop 2 gives me the same thing except:

GPU: XFX 5850 XXX edition

mobo: MSi p55 GD65

HDD: still 500 GB but changed to samsung (again, don't know which model)

Silverstone 750w PSU

NO CM hyper 212+

So shop 2 still gives me the same CPU, case and RAM with slight tweaks to the other parts at $1300 AUD
Now i want to get the Asus p7p55d-e pro
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621&cm_re=asus_p7p55d_pro-_-13-131-621-_-Product

which is gonna cost me an additional $130 and make the total cost up to $1430 AUD here
The shop guy don't really recommend the asus mobo cuz he said i better spend that $100 on something else


Shop 1: $1450 Shop 2: $1300 ($1430 with the asus mobo


Shop 2 also said that silverstone psu are better than corsair...

I have always been a big asus fan. 650w PS should be enough but 750 bout the same so why not. What are you doing with this thing? Gaming?

 

[Silvune]

I would go with option 2. Subject to finding out exactly which model of Silverstone PSU is being offered OR getting a good 650W PSU in it's place. Hopefully this change will give you some more money to alter other parts in the build. You could make the same change to the first build as well.

I suppose it's possible that the extra $100 could ensure that you get a fast harddrive and get you CPU cooler. The MSI P55-GD65 is a good board, but the Asus P7P55D-E Pro has the advantage of SATA 6Gbps. The MSI board is much better than the Gigabyte board in the first build.

If you are going to overclock then you probably would want to get the Hyper 212 Plus. Otherwise it's not very important.

 

[geofelt]

Here is a vote for option 1.

1) A corsair 750HX PSU is about as good as it gets. But, do you really need modular, or that much power? A 650 watt unit will power the strongest single graphics card you can buy today. Modular is OK, but with a properly sized psu, you will be using most of the leads anyway. It is not hard to tuck the unused leads away.
2) The gigabyte motherboard is good, and it includes usb 3.0 and some 6gb sata ports. What more features do you need? Your cpu will run the same speed, regardless of the motherboard.
3) You get a decent oem cpu cooler. It is best to install one during the initial build while the motherboard is still out of the case. Your PC will run cooler and quieter and if you OC, you
can go higher and easier.
4) The XFX 5850 is a bit better. It is the factory overclocked version and XFX has a double lifetime warranty. (Is this still true in Australia?) I do not see the performance difference as significant.
5) Check on which version of WD hard drive is offered. The green is slower to be more energy efficient, the black is the best performer, and the blue is in between. I would opt for the black which is slightly more expensive. Perhaps even the 1tb model which is a bit faster.
6) If you have some extra budget, consider a intel X25-V 40gb SSD(or two) for your OS and a few games. Newegg had them on sale here for $98. Anandtech had a glowing article on this. http://www.anandtech.com/show/3618/intel-x25v-in-raid0-faster-than-x25m-g2-for-250

See if each shop will adjust it's bid to your specs so you can compare them directly.

turns out I'm going to go with Shop 3...

Intel i5
Asus p7p55dd-e pro
ASUS 5850
4GB DDR3 G.skill Ripjaws 1600
Corsair HX 750
500 GB Seagate HDD
Haf 922 / Antec 902

this for $ 1404 ( $1391 if i go for the Antec)

I can also save some mre $$ by going with 650w but i might crossfire these 5850s in the future... and lightly OC my i5
will it still be enough?
i can save $47 by going with a corsair HX 650

Theres also the Seasonic M12D 750w $20 cheaper than the HX 750

 

[Silvune]

Yea, I advise changing the power supply to either the Seasonic M12D or HX650. As the Seasonic will be a very good power supply. And yes a 650W power supply is plenty for two 5850s and an overclock.
