$575 gaming computer, semi-final build... suggestions?

[whitefang]

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=N82E16819103300

MotherBoard: Asrock A780GXE http://www.newegg.com/Product/Product.aspx?Item=N82E16813157139

Ram/Memory: G.SKILL 4GB DDR2 1066 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231241

VideoCard: Sapphire 4830 http://www.newegg.com/Product/Product.aspx?Item=N82E16814102822

PowerSupply: OCZ fatal1ty 550W http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022

HardDrive: WD 320GB 16mb cache http://www.newegg.com/Product/Product.aspx?Item=N82E16822136074

case: CoolerMaster rc-690 http://www.newegg.com/Product/Product.aspx?Item=N82E16811119137

Heatsinkfan: Rosewill RCX-Z940-SL http://www.newegg.com/Product/Product.aspx?Item=N82E16835200023

Crossfirebridge: http://www.newegg.com/Product/Product.aspx?Item=N82E16814999002

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?

 

[whitefang]

Oh, is there any other good cases like the coolermaster Rc-690 for a better price?

 

[Helloworld_98]

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.

 

[whitefang]

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:

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.

 

[whitefang]

Ok, there's this ASUS motherboard that just came out, no reviews of it yet... is it risky to try it? same price as asrock except the second PCI-Express slot is at x4 speed instead of x8 speed, does that affect it alot?

it will on a 4830.

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

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.

Yup, that MB is a bad idea for Crossfire. It would be like running Crossfire on a P35 motherboard - it hurts a lot.

 

[aevm]

Here's a good MB for $110:

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!

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.

 

[whitefang]

*edit* lag, double post.

 

[whitefang]

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?cPath=18_37_3&products_id=103 OR this one http://cmstore.coolermaster-usa.com/product_info.php?cPath=18_37_3&products_id=102

 

[aevm]

You could add the aftermarket cooler later, I guess.

I'll try to find you a cheaper PSU.

Those RealPower PSUs are decent. Definitely better than other CoolerMaster PSUs. However, I don't like the "refurbished" part, it sounds risky.

Here's a StealthXStream 600W for $60.

or a Corsair 550VX for $66

[whitefang]

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!

 

[aevm]

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.

 

[whitefang]

Ok well I might just get this one.

Antec 650W 3 rails 22A 22A and 25A http://www.newegg.com/Product/Product.aspx?Item=N82E16817371015

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!

 

[xthekidx]

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.

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.
