I had another post about this but every time I click the post I get an error so I am reposting.

*NOTE* I already have a 4830, I plan on buying another to Xfire with it, and I have a monitor mouse and keyboard, I have a DVD-rom, and I have an operating system.

I plan on gaming at 1600 by 1200 resolution, I intend to play crysis on high settings.

Here's my build so far.

Processor: 7750 kuma 2.7 ghz http://www.newegg.com/Product/Product.aspx?Item=N82E168...

MotherBoard: Asrock A780GXE http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Ram/Memory: G.SKILL 4GB DDR2 1066 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

VideoCard: Sapphire 4830 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

PowerSupply: OCZ fatal1ty 550W http://www.newegg.com/Product/Product.aspx?Item=N82E168...

HardDrive: WD 320GB 16mb cache http://www.newegg.com/Product/Product.aspx?Item=N82E168...

case: CoolerMaster rc-690 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Heatsinkfan: Rosewill RCX-Z940-SL http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Crossfirebridge: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Total comes to $562 including shipping

What do you guys think? will the processor bottleneck the video cards? will the heatsinkfan be able to overclock the processor?
April 9, 2009 4:00:37 PM

Oh, is there any other good cases like the coolermaster Rc-690 for a better price?
April 9, 2009 4:09:23 PM

RC-590 is close.

Also there isn't a HDD and asrock's aren't the best mobo's out there, try gigabyte or asus.

Oh oops, I'll edit that, (forgot to post link, price is still the same)

You could get a high-end HDT-S1283 cooler for $27 after rebate:
http://www.newegg.com/Product/Product.aspx?Item=N82E16835233003

Do you like the Antec 300 case? Anyway, I'd prefer the the RC-690 myself.

That PSU is powerful enough for what you're planning, but barely. I'd recommend spending an extra $5 (after rebate) and getting a Corsair 650TX. That leaves more room for overclocking, TV tuners, hard drives, whatever.

Add a WD3200AAKS hard disk.

it will on a 4830.



Yup, that MB is a bad idea for Crossfire. It would be like running Crossfire on a P35 motherboard - it hurts a lot.
April 9, 2009 5:38:56 PM

I think the OCZ PSU will be fine for 4830's xfired, its got 50A on the 12v rails which is pretty good.

$50 for CM RC-690

Wow you just made my day! that's $37 saved and I mean EVERY penny counts, I can't buy my thermal paste for now because I am so low on cash (Don't have a job here) but now I might just be able to get it.

Thanks!

Here's a combo for AMD X3 720 + the Sapphire HD 4830:

http://secure.newegg.com/Shopping/AddToCart.aspx?Submit=ADD&ItemList=Combo.183511

That means you end up paying $117 for the X3 720. I think it's worth it. It's more future-proof than the $65 dual-core.


Wow this is a good deal, the kuma went to $72 so the kuma isn't as good of a deal.

but now that I saved $40 on the case I can get this now, awesome.
April 9, 2009 6:06:35 PM

*edit* lag, double post.
April 9, 2009 6:17:11 PM

Ok, The price is still too high for my liking with the new processor ($581) I really need it around the $550 range (575 was the max limit unless a REALLY good deal came along)

I could go with this price, but is there any other way to make it cheaper? Do I really need that good of a PSU or can I get a different one?


*edit* since I am already buying the case from CM website, is this a good power supply? it would save me $25 http://cmstore.coolermaster-usa.com/product_info.php?cP... OR this one http://cmstore.coolermaster-usa.com/product_info.php?cP...
April 9, 2009 6:23:34 PM

You could add the aftermarket cooler later, I guess.

I'll try to find you a cheaper PSU.
April 9, 2009 6:34:06 PM

Yeah I should just stay with the fatal1ty.

Ok I know this contradicts everything I have been saying about money, but how much more would it be to get a PSU that could handle 2 4870's in CF?

Is there any chance the fatal1ty could do it?

Thanks!
April 9, 2009 6:44:17 PM

It could do it, with some molex-PCI-E adapters, and pushed rather too close to max (i.e. with extra heat and noise and lower efficiency). I'd recommend a 750TX for that sort of thing.

+1 I wouldn't do 4870's on the fatal1ty 550w. 4850's might be ok.
April 9, 2009 7:06:31 PM

It would be iffy I think. You will still need molex connectors because the 4870's require 2 PCIE connectors each, 4 total. You would still be running at lower efficiency, close to the max on that PSU. Running a PSU maxed out shortens its life, similar to overclocking a CPU or GPU. But I do think its a better option than the Fatal1ty if its the same price or cheaper.

Nah, it's misleading marketing. It adds up like 25A+25A=37A combined. Not so good any more. I think it will do too, but it leaves much less room for upgrades than it looks.

Ok well I might just get this one.

Antec 650W 3 rails 22A 22A and 25A http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If only it were modular...

This will be enough power for 2 4870's right?


*EDIT* Haha, a dollar cheaper then fatal1ty because this one has free shipping!


It has 45A combined. Definitely better than the 37A of the Fatality PSU. Still, a 650TX at 52A or a 750TX at 60A would make more sense. Try www.buy.com too, they often have good PSU prices.

Some HD 4870 cards come with molex-to-PCI-E adapters. For example a 650TX has 2 PCI-E connectors, and HD 4870 Crossfire needs 4, but you get the missing adapters for free with the card. I think Sapphire includes adapters, for example.

April 9, 2009 7:15:17 PM

Is the fatal1ty better then the antec 650 in any way? except for it's modular bonus.

and I am geussing it's a really bad idea to get this PSU

How does that work?
April 9, 2009 7:28:58 PM

That's something i also would like to find out, is how that works on multi-railed. 25a +25a = 37a?..

April 9, 2009 7:41:57 PM

Stay away from the raidmax.
April 9, 2009 7:48:03 PM

Raidmax PSUs blow up when loaded to 75% of their claimed rating.
http://www.corsairmemory.com/cinema/movie.aspx?id=62274...
I would NOT buy the OCZ Fatal1ty, especially for multiple GPUs. I've not seen any competent technical reviews on it (e.g. jonnyguru), and it's made by Sirtec.
Antec, Corsair, PC Power & Cooling, or Seasonic would be the way to go. The EA-650 you linked should do nicely.
April 9, 2009 7:53:35 PM

To explain the non-additive +12V rails...

The +12 on most PSUs comes from a single source, which is rated for some maximum amount (e.g. 37A). Each virtual rail that branches of off it is current-limited to a lesser amount (e.g. 20A). So, there could be 2-3 (or more!) virtual rails, and you can pull up to the lesser amount (20A) from any of them, so long as the TOTAL on all the +12V rails does not exceed the maximum. Make sense?
April 9, 2009 8:00:25 PM

Lots of good info to know, I think I am going to get the antec 650W, too bad it's not modular.
April 9, 2009 8:02:41 PM

Makes alot more sense then looking at numbers. Is that why at higher wattage multiple rails would be more beneficial? as in 1kw or higher?
April 9, 2009 8:08:31 PM

Neither of those processors is likely to overclock very well. The X3 720 would be a better choice if you go AMD.

And no, I can't see your cart; it shows mine, which is currently empty.
April 9, 2009 8:10:23 PM

Old phenoms OC like crap, I wouldn't bother trying with them. You might get .4 more GHZ if you are lucky. Newer Phenom II's and Intel CPU's are much better at OC'ing.

Posting the link to your shopping list doesn't work, it just takes everyone to their own shopping list.
April 9, 2009 8:12:06 PM

Ok link doesn't work for others, here's a wishlist that should work

*NOTE* the case is not the case I am buying, I am getting the CM-rc-690 case, I put that case there because it's the same price as the CM-RC-690 from CM.com

http://secure.newegg.com/WishList/TemporaryWishList.asp...

That processor? or should I go for the 4830 + x3 720 for $206 aevm suggested?


*EDIT* ok xthekidX I geuss that processor is not a good idea, I geuss I'll have to go for the combo aevm suggested, I just hate to use so much money.
April 9, 2009 8:16:34 PM

This setup is only possible for that amazing deal on the rc-690, I am excited.

lol You cant post a temporary wishlist either, it just takes us to our temp wishlists. You have to make a saved wishlist then make it public so we can all see it. Third time's a charm.

Lol ok thanks.

oops one second, error on page for me editing it.
April 9, 2009 8:31:30 PM

I would get the 720BE over the 9950. That processor does not OC very well, you might get .4ghz more out of it if you are lucky with a good CPU cooler, the cooler you chose won't be able to handle it I don't think.
April 9, 2009 8:42:34 PM

There are better options for a case, that one will be cramped, not to mention will not fit your mb since its a mATX.
April 9, 2009 8:44:11 PM

that's not the case I am using, I am using a rc-690 from Coolermaster

I just used that one because it's the same price as the rc-690 and newegg doesn't have it, I am buying it from coolermaster.com
