ASUS P8H67-M EVO or P8H67-M PRO

[jaquith]

I can use Google translation so it's not the language, the problem is using those sites and then converting the currency. I 'know' what's good (value) in USD, but since the prices don't match-up is takes 5X~10X the time.

Also, I'm not the best guy for budget PC's...so in this situation I can render an opinion if asked.

 

[staurulinos]

You have done more than enough, I am gonna gather more opinions about the motherboard i should choose

 

[staurulinos]

since i cant get any help from other people, do u think that the ASUS P8H67-M PRO REV3.0 is worth the money or should i buy another Motherboard?
I bought the Sapphire HD 6850

For a non-(K) SB/IB CPU the H67 is fine -- it won't allow any OC'ing CPU nor RAM (DDR3-1333). The newer ASUS P8H77-M PRO allows you to OC the RAM i.e. run DDR3-1600 but not the CPU; more info - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8H77M_PRO/#specifications

 

[staurulinos]

i think i am gonna go with some of these :
ASUS P8Z77-M - 110 euros
P8Z77-M PRO - 135 euros
P8Z7-V LX -125 euros
P8Z77-V LE - 149 euros
(i am looking on a variety of websites..)

My general preference is not to go the mATX route and the third is a typo but if the P8Z77-V LK is in your price range I like the x8/x8 it offers - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z77V_LK/#specifications

Spoiler

i can even find the P8Z77-V LK in Greece the fourth one was a typo mistake, i meant :
P8Z77-V LE - 149 euros

Hmm...that's a shame the P8Z77-V LK is a very good value especially for CF. Then the ASUS P8Z77-V LE because it also offers x16 and x8/x8. In the US the ASUS P8Z77-V LE is $40 more with essentially the same offerings as the P8Z77-V LK.

P8Z77-V LE - 149 euros

 

[staurulinos]

I am concerned whether the P8Z77-V LE is worth the extra 25 euros ~ 31 dollars than buying the P8Z7-V LX

 

[jaquith]

Today no -- tomorrow probably.

One more thing, i may want in the distant furure to upgrade my pc.
So, i may buy a used HD6850 and set up a crossfire, but i am worried that the PSU wont be able to supply me with the wattage my computer will need.I 've completed the corsair's power consumption calculator and it says to me that i will need a 750W psu.
(i dont believe that the eXtreme Power Supply Calculator is telling the truth since it says that 4 crossfired HD6850 min consume is 381W while in the site above, it says that 2 crossfired HD6850's consume around 393W)
the site mensioned: http://www.guru3d.com/article/radeon-hd-6850-6870-crossfirex-review/4

What do you think?

 

[staurulinos]

Bear in mind that i have chosen :
Inel i5 3570K
Radeon HD 6850
2 DDR3 RAM sticks
3 fans with leds + 1 for the CPU Cooler withould any leds
1 DVD/CD-RW Combo

and i will have about 4 usb devices

I dont know whether you have a calculator you trust thats why i give you those details.

 

[staurulinos]

i found Thermaltake Toughpower XT 775W for 108 euros
and OCZ Fatal1ty 750w for 99 euros
both were suggested from a website (dont remember exactly how it was called) and both are expensive

Replies:
1. CF 6850 what you're looking at is the total power consumption and not the GPU's themselves which according to link you provided is "~ 245 Watts" and at best that's a good guess. To be on the safe side I'd look at a 650W PSU and sure bigger is fine.

2. OK

3. I don't like any of those PSU's. Get either Corsair or SeaSonic also Enermax is good. No, I won't say okay to others and that's on your shoulders.

 

[staurulinos]

So, a 650W or better psu will handle 2 6850's
Thanks very much once more.

 

[jaquith]

Yep.

Radeon HD 6850 x2

A second card requires you to add another ~130 Watts. You need a 650 Watt power supply unit.

[staurulinos]

i am gonna go with the corsair gs700

 

[jaquith]

Very good!

 

[staurulinos]

One last question, you mentioned that the P8Z77-V LK is a very good value especially for CF.But isnt the LE the same as good as the LK?

 

[jaquith]

No, the 'LE' is not an x8/x8 MOBO and is ideally suited for a single GPU. Using either CF or SLI you want the PCIe to be x8/x8 for optimum performance, and you want to use the PCIe slots that are optimized for the 'PCIe graphics' to the CPU.

P8Z77-V LK - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z77V_LK/#specifications
2 x PCIe 3.0/2.0 x16 (x16 or dual x8) *2
1 x PCIe 2.0 x16 (x4 mode, black)

P8Z77-V LE - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z77V_LE/#specifications
1 x PCIe 3.0/2.0 x16 (blue) *3
1 x PCIe 2.0 x16 (x4 mode, black) *4

 

[staurulinos]

Well that sucks because the nearest shop that sells this motherboard is about 320 miles awayso. shipping is the only choice i've got and it will be difficult to return the product if i come across any problems.
I read that there are only 2~3% in FPS difference between 2x8 and 2x16 so if it is only that low i will probably buy the LE

 

[jaquith]

The LE is x16/x4 (none Graphics lanes) the LK is x8/x8 on the PCIe Graphics lanes.

I would look at Corsair or SeaSonic PSU's - less chance of coil whine. Simply, the cost burden to OC a CPU is more costly than not OC'ing a CPU - components have to dissipate more heat, provide more power, and 'even/smooth' power: MOBO, CPU, HSF, PSU.

Good Z77's (OC + CF/SLI):
ASUS P8Z77-V *
ASUS P8Z77-V Pro *
ASRock Z77 Extreme4
ASRock Z77 Extreme6
Gigabyte GA-Z77X-UD3H
Gigabyte GA-Z77X-UD5H *
/I'm not an advocate of MSI/
* - better OC'ing.

RAID is simply when more that (1) HDD/SSD are used together. RAID 1, 5, 10 use redunency and RAID 0 places together two or more drives to increase performance but the down side is if you lose any drive you lose all data. More info - http://en.wikipedia.org/wiki/RAID

SLI (Scalable Link Interface) - pertains to nVidia GPU's only 2/3/4-WAY SLI (2-4 GPUs). More info - http://en.wikipedia.org/wiki/Scalable_Link_Interface

SATA (Serial ATA or Serial AT Attachment) - is the communication interface of current consumer based 'drives': HDD, SDD, ODD. More info - http://en.wikipedia.org/wiki/Serial_ATA

Hello the mother Asus P8Z68-LX is good for O.C core i5 2500k or better ASUS P8Z77-V?
