AMD Phenom II X3 720 2.8 ghz 3x512kb Tri-Core

Antec 300

Corsair 400CX 80PLUS 400watts

Kingston™ dual 4g ddr2 800

Seagate 500gb/16mb 7200.12 (ST3500418AS) sata

LG™ 22x dvdrw dual layer sata ls lightscribe

Powercolor ATI HD 4770 512mb (128bit) GDDR5

EMAXX AMD790GX-XTRM

Arctic Cooling (Freezer 64 Pro) AM2 PWM

Arctic Cooling (MX-2) high performance thermal

Do you think the power supply i picked is good enough? even for two 4770's?

*Emaxx is a rebranded J&W mobo. It's the same as this one:

Well could you specify from where you will be buying those components from...
The setup looks good...
But I doubt the 400W would be suffice for dual 4770s...get atleast 500/550W above psu with 2x 6 pin connector...
May 6, 2009 6:23:24 AM

Seasonic S12 II 430W or Enermax Pro82+ 425W both have 2 PCIe connectors and would be plenty of power.

You don't need the MX-2, it comes pre-applied to the cooler.

I would spend a little more,just to be safe,and get a 550watt PSU with 40+amps on the 12volt rail.A good rule I use when buying a PSU is to get one with 25%-50%more power than what would just get you by.Doing this insures good,clean power and less load/stress on the PSU itself,giving you a longer life on the psu,with less chance of errors resulting from too little power.Goodluck.

If you looking for a budget 790GX have a look at Biostar TA790GX 128/XE and Asrock's offering - i'd rate these higher than the one you picked out

2 HD4770s only use ~100W.
May 6, 2009 6:57:37 AM

I am located in the Philippines. I am buying the parts at a local shop here at slightly higher costs than in newegg. Total cost is around $710 USD.
About the PSU, do you think that changing it to a Corsair 450HX would suffice?
I am also considering changing the motherboard to a foxconn a7da. Any comments on this? Thanks! really appreciate your inputs.
May 6, 2009 6:59:55 AM

Well could you give what other options are available for you with the mobo, PSU...
May 6, 2009 7:01:51 AM

Well checking the Corsair 450HX, it has 2 6+2pin...So it should do the job and is modular too...
May 6, 2009 7:04:35 AM

Thanks gkay! How about the foxconn a7da mobo? I read a review on it on another site and apparently he recommends it. thanks
May 6, 2009 7:11:53 AM

Well the Foxconn a7da is a good board...but the Gigabte and the ASUS ones are better...See if you are able to get any of these boards ...

GIGABYTE GA-MA790X-UD4P
GIGABYTE GA-MA790GP-UD4H
ASUS M4A78-E
ASUS M3A78-T

If not stick with the Foxconn...
May 6, 2009 7:13:15 AM

But note that the GIGABYTE GA-MA790X-UD4P doesn't have on board video...
May 6, 2009 7:21:09 AM

Noted. Thanks again gkay! will try to find one of those gigabyte boards you listed.
May 6, 2009 7:36:52 AM

:) 
May 6, 2009 7:54:23 AM

ok, so the gigabyte 790x is about $160+ here. the 790gp is about $190+, while the foxconn a7da is only about $100+. I would rather get the foxconn, as the money i save here could be used for another 4770. what do you think?
May 6, 2009 7:58:28 AM

Yes less mobo , more GPU = more frames so you on the right path hehe
May 6, 2009 7:59:11 AM

Thanks man! :) 
May 6, 2009 8:01:59 AM

One last question, the RAM i picked are the ordinary ones (value series). Do I need better ram to OC my proc to 3.4ghz?
May 6, 2009 8:13:08 AM

To 3.4? Nah use multi and up Vcore if you have to
May 6, 2009 8:28:53 AM

ok thanks again man!
May 6, 2009 8:44:27 AM

Well like batuchka said you wont need high performance RAM for that overclock...but it would be good if you buy RAM with heat spreader on it as it would keep the RAM cool and would be more stable...
May 6, 2009 9:14:20 AM

ok got it, thanks!
May 6, 2009 10:28:57 AM

I would go with a bit more psu

couple of other comments

I noticed you said dual 4g ddr2 - 800 kingston RAM
If you are saying you put in two 4gb kits that is, imo, wasted money. if it is just a misunderstanding and it is only 4gb total then cool. If it is indeed 8gb you are looking at then I would suggest dropping it to 4gb w/ tighter trimmings and or going 1066

next i'd think with the rest of your components your GPU selection is a bit light. Don't get me wrong a 4770 is a nice card and I would love to get one personally but , the rest of your specs over match it. Yes if you want to crossfire them it would be way sweet but until you do I think you will be wanting a bit more (unless you are running a 1280x1024 res on a smallish screen).

My opinion drop the extra $50 for the 4870.

If you are dead set on the 4770 i'd say go with a FX mobo w/ 3 or 4 pci-e slots. tht way when you do upgrade to a crossfire setup you have 2 running @ full 16x16. and room for another @ 8x for future .
Even still w/ the FX I still like the idea of a single 4870 better which will leave an open 16x slot for another down the road.

May 6, 2009 10:50:46 AM

Well t0r0 he is not from US...
And the mobos that you are specifying would cost him much as those are high end boards and in other countries, they come at high premium...
And as for the 4770, he could still add one more on the above boards to improve performance...
May 6, 2009 11:01:17 AM

buy it now 790fx am2/am2+ board $166 nd there are a bunch more like it.

http://cgi.ebay.com/MSI-NEW-K9A2-Platinum-AM2-AM2-AMD-7...

The idea is that for the small extra cost now( he is already looking at $160 boards) the life extension on the gaming rig is one whole 16x extra card minimum for a 3 slot board. compared to a gx board that only has 1 full 16x slot.
May 6, 2009 11:04:23 AM

Well one more thing that I would like to clear is that there is no significant real world performance difference when cards run in x8x8 and x16x16 mode...
It will just be very few fps drop, which is not noticeable...
And the mobos he has chosen all have 2 or more pcie slots, thus having an option of future crossfire...

And he is from philippines so getting items from ebay US can pose problems...
May 6, 2009 11:26:30 AM

there is no significant real world difference now, but a GPU or 2 down the line maybe a different story.

maybe the problem here is I look at my system builds from a future perspective, the mobo most of all. looking at a system w/ the gx chipset running at 8x8x as a platform doesn't seem like he best option to me. When you are looking at a lower end card like a 4770 you know you are going to be stopped at
2 4770 which should last a while but with the fx board you don't have to stop there a 3rd or a 4th $100 card is a cheap upgrade or you have the option to go heavier with a next gen card that requires a 16x slot. sure you say the gx can do that but then you are stuck there.

and yes you can speculate all you want about availability of fx boards and ebay availability around the world but until the originator says gee I can't get that here for a reasonable cost it is just that, speculation.
May 6, 2009 11:35:38 AM

Well I would partly agree with changing 4770 to more powerful card but that is left to the OP as it would be limited by his budget...
But still I think there is a long time until the graphics card would start utilizing the x16x16 bandwidth...and by then he might buy a new PC who know...
May 7, 2009 6:16:40 AM

a cf or sli don't give you double the performance
http://www.techspot.com/review/139-geforce-gtx-295/page...

i think a gtx260 or 4870 is a better fit on your system..

go for bigger watts if you plan on upgrading..

you can buy the coolers later if you're on a budget.. (just don't overclock without those):D
