Hi guys,

I'm building a new system and almost had my mind set on a 1156 system but now that i7-920 is 200$ @ Microcenter again, I'm having second thoughts.
An 1156 system would come out to about 500-550 dollars depending on the processor with RAM.

Can somebody recommend a good X58 motherboard and triple channel RAM?

If the prices are about the same I'm really thinking about switching to X58...

More about : 860 920

They aren't. You'll spend an extra $50-100 on the motherboard and another extra $50-75 on the RAM.

What are your plans for the build? You might want to follow the guidelines from the link in my signature. By answering those simple questions, we can probably vastly improve your build, or at least find cheaper parts.

EDIT: Forgot to add the suggestions: Asus P6X58D Premium ($310) and G.Skill 3x2 GB 1600 mhz CAS Latency 7 ($170).

APPROXIMATE PURCHASE DATE: this week
BUDGET RANGE: less is better :) 

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: programming in Java, C++, gaming, internet, movies

PARTS NOT REQUIRED: N/A

PREFERRED WEBSITE(S) FOR PARTS: newegg.com
COUNTRY OF ORIGIN: USA, California

PARTS PREFERENCES: ATI, Intel

ADDITIONAL COMMENTS: will be visiting US next week and picking up these components, therefore RMA-ing is a bit of a problem

Proc: haven't decided between i5-750 (180$) and i7-860 (230$), both @ Microcenter

Mobo
torn between these:
ASUS P7P55D-E Pro LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard - Retail

and

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

Worried about high-pitched noises on ASUS board mentioned in a couple of reviews so am inclined to go Gigabyte although I really like 3.0 features implementation on ASUS... any thoughts?

RAM
thinking about these:

Again need suggestions...

HDD

PSU

Any advice is welcome... concerning the X58 setup, if the difference is over 100$ it's not worth it...
Thx for the help...

EDIT: just saw your edit... it's definitely over 100$ :)

I haven't heard anything in official reviews about the Asus board's sound. I believe it's a problem that's being attributed to it in user reviews by people who don't know better.

The problem with the Gigabyte board is that if you were to Crossfire, you would lose the USB 3/SATA III benefits. That's not the case on the Asus board. So being about the same price, go with the Asus.

RAM: The first set is the best performance. However, there is a set of Corsairs that have the same specs for $110.

HDD: That's the best one.

PSU: That unit is good, but will not support Crossfire. You'd need at least a 750W unit. My personal favorite recommendation in that range is the SeaSonic 850W for $110. It's more expensive, but it's a large unit that will handle anything. It's also extremely efficient and it's made by one of the highest quality manufacturers.

CPU: Here's where I'm not too sure. If it was strictly gaming, the i5 would be the definite choice. However, I don't know how much your other activites rely on hyperthreading. I'm leaning towards the i7 mainly because it's as good as the i5 in games, but much better in pretty much everything else.

As it is somewhat under contention, I've gotta vouch for that X58 Premium Board from Asus. I've finished a build I posted here some time ago, and I'd had issues with EVGA (customer support was great, product quality, ...).

Don' t know why ppl have such a hardon over the i7-920. It is worse at gaming than an i5. Worse at everything vs an i7-860.
http://www.tomshardware.com/reviews/quad-core-cpu,2499-...
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=363...

It's 4% FPS increase w/ xfire due to dual x16in gaming is negated the 860's better performance, or completely negated by using a 5970.
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=364...

i7-920 only ties a Phenom II x4, half it's price, even with a 5970.
http://www.legionhardware.com/document.php?id=869&p=23

i7-920 has horrible minimum frame rates. Worse than even Core 2 Duo and Quads in some games. P55 CPU's and AMD Phenom II's don't.

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=363...

Triple Channel offers no difference at worse, a only discernible in benchmarks difference at best.

P55 chips use less power and run cooler than x58.
http://www.tomshardware.com/reviews/intel-core-i5,2410-...

The only advantage of the i7-920 is that you can upgrade to an i9 later this year. The questions is, after buying a i7-920 for nearly $300, do you really want to upgrade to a estimated $600 chip within the year?

If not, both x58 and P55 will be outdated in a year when 22nm sockets come out.

I have an i7-920 system and an i5-750 system. The i7 was great when I built it a year ago. Currently, I see absolutely no reason to go with x58.

That's what I was thinking also... on the other hand I've been reading about poorly made capacitors that can cause buzzing noises in almost all components. Last review on Newegg says that ASUS customer support claimed it's probably just a bad batch... sucks that you have to rely on luck for a 200$ component. On one hand I like ASUS more but on the other hand RMA-in is somewhat of a problem if it turns out to be a real issue...

Read that G.skill is the best now, but that Corsair also looks good... someone on this forum noted that 1.65V is a bit high and 1.5V is more suited for P55?

Don't know if and when I'll be crossfiring but will definitely take that PSU into consideration, thx...

Concerning the CPU... similar to what I'm thinking, when investing this kind of money skimping on 50$ doesn't seem wise... better to later find out that I didn't really need the i7 ;) 

@banthracis
Realize that P55 CPU's is currently superior to i7-920. Only thing going for the I7-920 is future proofing. But like you said I don't intend to upgrade again in the next 3-4 years and then it definitely won't be to a 600 dollar chip. Also by then I will probably have to change the mobo as well...
What can I say, moment of madness ;) 
Nice presentation btw...

Hi,

Just put together the above build and it works great, first post with no problems. Thx to all for the help...

Only thing bothering me is the Intel stock cooler. Started Win 7 system rating and about half way through ASUS Probe (app for system temp supervision) started an alarm that the CP is over 60 degrees C. So I'm worried that it will get too warm when I start more demanding apps like Prime or games.

Do I need an aftermarket cooler? If so which one?

Noticed the review on THG singling out CM Hyper 212+ and Scythe Mugen-2 Rev. B. Any recommendations?
February 12, 2010 12:44:41 PM

Hyper 212 + is what I've been using. They work great, similiar system temps ins high 20's on idle, high 30's on load w/ a Element G case.
