Hi...

I like to know the comments about the gaming rig i'm planning to build.


AMD Phenom II X4 965 Black Edition,3400MHz ,Quad Core, Sockel AM3, 8MB Cache, 125 Watt
ATI Radeon HD 5970 , 2GB DDR5, 735MHz, PCI-Ex16 2.1, DVI, Dual GPU 735MHz, MEM 4040MHz 512bit
Gigabyte 890XA-UD3 , ATX, AMD790X, 5200 MT/s, AM3, 4xDDR3(1866)/1333/1066MHz, 2xPCI-E V2.0, G-LAN, SATA3.0, SATA-RAID 0/1/5/0+1, 2xPCI-E x16 (16x, 8x), FireWire, USB3.0
Corsair XMS3 Dominator 4GB 2-Kit Phenom II DDR3 1600MHz CL8
Western Caviar Black 3,5"-HDD, SATA-III, 1 TB (1000 GB), 7200 rpm, 64 MB Cache, OEM
Coolermaster Cosmos 1000- Case

I'm confused about the PSU. Which is the best PSU for Radeon 5970?
And the CPU cooler. Which is the recommended one.

Like to know the possible modifications in the above configuration...

Any reliable PSU that can deliver the necessary power will be a good candidate. So, get a Antec/Corsair/Seasonic that's at least 750W, and you will be fine. This is beacuse the HD5970 has a TDP of just over 300W and the mobo + CPU use 50W. You also have RAM sticks and other devices which contribute some more watts. This is at max load, though.

The stock AMD CPU cooler is good, so if you don't plan to overclock, you can save a bit of money there. However, if you really like quietness or want to play with the higher ends of overclocking, get a CoolerMaster Hyper 212.

you mean a corseair 650w is enough for this? and what are the other good cases which gives a good cooling?
April 9, 2010 2:19:55 PM

Yep, you can get the Corsair 650HX or Antec or Seasonic.

Cooler Master CM 690 II Advanced, Cooler Master HAF 922, Antec Nine Hundred II, Lancool PC-K62, Zalman MS1000-HS2, Antec Twelve Hundred.

You will have to make sure that the case you choose can fit a 5970 as they are very long. The Cosmos 1000 can fit it, whereas the CM 690 II Advanced, Lancool PC-K62 can't, the HAF can, a 5970 can fit in an Antec 900, not sure about the 902. I don't know about the other one mosox suggested.

750W is good but too big for a single card and too small for a crossfire. His mobo doesn't have crossfire x16 either.

hi mosox..my mobo supports x16 PCIE. And in future may be after 1 year if, if i want to crossfire it, then i think 850w is better. right ?
April 9, 2010 5:39:37 PM

Your mobo supports only one card running at x16 or two running at x8 (seriously limiting a 5970). This one supports 2 cards running at x16. For crossfire you will need a 800+ PSU.

But on the other hand, a single 5970 is so powerful that by the time you'll need to add one more there will be many other more powerful cards on the market to replace it with so scarp the crossfire and go cheaper.

April 9, 2010 5:50:56 PM

No, crossfire 8x8 is only 4% performance reduction from 16X16, no point in switching.

a quality 750W can support two 5970's.
April 9, 2010 6:26:28 PM

That was shown numberous times on a 5870, I have not seen this shown on a 5970, so if you've seen something I haven't then I'd appreciate if you pointed me in the right direction.
April 9, 2010 6:36:03 PM



i dont think you would wanna hook up 2 5970's to a 750 watt

304+304=608 watts + i7 130 watts = 738 watts - 750watts = 12 watts <<< i wanna see you run a few fans,hdd and mother board on 12 watts

This is the url to my mobo :
http://www.gigabyte.com.tw/Products/Motherboard/Product...
It says "2 PCI-E 2.0 x16 interface with ATI CrossFireX/ Hybrid CrossFireX technology support "
April 9, 2010 7:30:59 PM

(Note 4) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When PCIEX8 is populated with a PCI Express graphics card, the PCIEX16 slot will operate at up to x8 mode.

You have to pay attention to this bit as well
Quote:
#1 1 x PCI Express x16 slot, running at x16 (PCIEX16)
#2 1 x PCI Express x16 slot, running at x8 (PCIEX8)
The second x16 is full speed, whereas x8 is reduced speed. For almost every card the reduced speed of x8 is insignificant, there is more of a question mark over this with such powerful and fast card as the 5970.

I've modified my configuration to this:

AMD Phenom II X4 965 Black Edition
Gigabyte 890GPA-UD3H. This is the latest board with the AMD890GX chipset (before Gigabyte 890XA-UD3)
Corsair XMS3 DDR* 1600 MHz, PC3-12800 - 4GB
Western Caviar Black 1.0 TB SATA-III
ATI Radeon HD 5970
Corsair 750w PSU (before Corsair 850w)
Coolermaster Cosmos 1000- Case
Sony DVD Writer

http://www.antec.outervision.com/PSUEngine is a good site for calculating the power requirements.
April 10, 2010 9:05:37 AM

It seems like the PCIE runs at x8 of Gigabyte 890GPA-UD3H board. Do you think this x8 will affect the speed of gaming ? Which is the best board for gaming, with the latest techonologies, like sata 3 and usb 3?
April 10, 2010 9:17:39 AM

The PCIe will run at x16 unless you add a second card. And there's no need to add a second video card since the HD 5970 is the fastest card out there and it's actually two cards (dual GPU).
April 10, 2010 10:33:52 AM

I'm using a 5970 with an i7-920 and 6GB of RAM with a Corsair 650W PSU. You don't need 750W.

Overclock your CPU and GPU and you will be at the upper PSU limit with 650w, 750W is good but if the 850W is like 10-20$ more get the 850W.

An OCd 5970 will suck 400w+.

TX850 or TX750 from Corsair. Or if you can, TX950 considering its low price. PSUs power decrease with time, after 5 years, the PSU will not meet its specs.

Your CPU sucks more power than a i920 also.

Ya, its the old phenoms that uses more. TX750 PSU depending on price. The TX950 on special is really good w/$. As I said, the 5970 is under-clocked to achieve 300w, when running@ 5870 default speeds 1.162v, it would suck ~400w.

In the future, just OC the 5970, 2x5970 is not significant right now.

Nice Motherboard :D 

btw You can fit a 6 core in that motherboard, considering they are <299$, its tempting. Thats if you can wait another week.

In current game no , maybe Bad Company 2 as it is using 4 cores efficiently. Future game will prolly benefit and considering the 6 core price starting 200$ and 300$ for the top chip 3.2Ghz , it looks very promising. Turbo boost will OC 3 cores to 3.6Ghz and down clock other cores when not used. 6 Cores 3.2Ghz at 125w is great.

Release date is around the 27, so 2 weeks to go. Waiting is better ;) 

Edit: Phenom II X6-1055T 125W TDP/6x2.8G/Turbo 3.3G ~200$.

I've checked the videos of cable management in youtube. And found that the Corsair 800D is the best. But it's really costly. Is there any other cases which gives good cable management?

Check this video of 800D... it's awesome cable management.

A Midi tower is enough for radeon 5970? Also... any additional cooling is required if i don't plan to overclock both CPU and GPU ?
April 11, 2010 10:55:01 AM

If it were me I would just go with the 850w for futureproof. Even if you don't add a 2nd 5970 you have the option. (especially since you picked a board with a 2nd pci-e 16x)

Also save $30 bucks and get a AMD 955. And raise the clock multi to 17.00x yourself.
It's literally the same thing.

Then use that $30 savings to get a Cooler Master Hyper 212 Plus
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And about the cases both Coolermaster Cosmos 1000 and 800D looks nice. But at $160 vs $300 there is an obvious winner.

And if you were going to run a$300 case you better be getting a 975 with 12 gigs, watercooling and 4-6 hard drives. Otherwise way way way overkill especially for an amd proc setup.

And bingo. Certainly he can go find a 16x and 16x board but that's more money there. What's 4% anyway in the world of two 5970s.

I never expect to see anyone running (4) 5970s but it's the first board I saw with two 16x 16x on my search.

As I said, Hex Core Phenom X6 is 2 weeks away and will cost 199$ for 2.8Ghz and 279$ for 3.2Ghz. Take the 199$ and OC to 3.4Ghz. For 20$ more you get 6 cores. And dont try running 2x5970 on a 750w Yes it will work, but for how long? Psu efficiency will start degrading by pulling more watts than necessary from the wall and the psu might fail at any time and overheat. ATis minimum spec for 2x5970 is 850w.

Whats the price diff. between the 790 and the 890 chipset? Anyway, you get USB3 , Sata 6Gbs with the 890.
April 11, 2010 3:52:38 PM

Hi elie...considering the expense of one Corsair h50, I think it's better to use the stock processor with a little bit overclocking and after one year change it to the 6 core. At that time it will be cheaper. Also i think i won't get much improvements in gaming because of the overclocking.
A 5970 is enough to play any game with high settings at least for one year ;) 

One H50 will cost almost half the prize of the Phenom. If i save that money i can buy a better processor next year.
