Motheboard for: x2 AMD 6850/i5 2500k

Hello,

I'm looking into buying a new motherboard and I was wondering what sort of motherboard should I buy? I need one with atleast 2 x16 PCI ports for my crossfire x2 6850 and one that supports intel i5-2500k. I'm looking for something thats of good quality and decent price.

I'm also wondering, does the fact that I live in a country other than the US will affect me in any way? We use 110-220V with 50hz. I have a PSU in mind that will support the required power but I need to know if the motherboard plays any part of the equation or not.

Lastly, what should I look for in terms of motherboards? Should I look for a certain amount of slots or something? Could a particular motherboard not fit into a specific case? I don't have a branded one so yeah

Note: I'm not buying a new computer, just upgrading the one I have. Also note I'm using it for programs like AutoCAD and gaming. (Current setting lags while zoomed in AutoCAD)

For 2500k and 2 X 6850 a good budget mobo is this : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
The PSU's have automatic switch , you can plug in 110V or 220V
ATX motherboards don't fit in mATX cases. If you have an normal ATX Mid Tower your mobo will fit.

And about your PSU question, it is designed that way to work. There is no problem for the mobo : )

My only concern with this is that it doesn't seem to have USB ports on the front (Correct me I'm wrong though)

Does it have 2 x16 PCI?

You ask 10 people then 10 opinions. In general I'll never get an LGA 1155 MOBO with less than 12 CPU Phases. Also, often enough the i7-2600K OC's better than the i5-2500K, and there's a few games and more Apps that benefit from Hyper-Threading.

Answers:
1. No, what country you live in and it's power is your PSU to transform to 12v DC. So 110v or 220v makes no difference.
2. You need at least 2x PCIe x8 slots, and adequate Phases to OC.
3. I typically recommend 'purposed' CPU/MOBO vs one size fits all. Most AutoCAD are done on Xeon plus ECC as a Workstation vs a PlayStation, but consumer models + chance of errors will work.

That all said, I'd look at one of these:
Z68:
ASUS P8Z68-V PRO/GEN3 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Gigabyte GA-Z68XP-UD5 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
EATX ; verify fit with case:
EVGA Z68 FTW 160-SB-E689-KR - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
(doodad) EVGA Z68 FTW 160-SB-E689-K2 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

P67:
ASUS P8P67 WS REVOLUTION - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

side-by-side (NewEgg glitch prevented the correct ASUS P8Z68-V PRO/GEN3 from being listed. Only difference is PCIe 3.0 switch) - http://www.newegg.com/Product/Productcompare.aspx?Submi...

For pure gaming I like either the EVGA Z68 FTW or ASUS P8P67 WS REVOLUTION. Otherwise either the ASUS P8Z68-V PRO/GEN3 or Gigabyte GA-Z68XP-UD5. Also it depends on how many 'future' GPU's you'll be adding. For your situation probably the ASUS P8P67 WS REVOLUTION is a better solution.

Would the one recommended by a few people earlier work?

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

It has 2 x16 PCI 3.0 which I assume means it can handle a crossfire system, it can also handle an i5 processor which I'm going to get. What else would I need to take note of in a motherboard? Assume I'm a total newbie at this please (Which, I am!)

It says it will.

The ASRock Z68 Extreme3 has 8 Phases to the CPU and 4 Phases to the iGPU which translates into a higher vCore = higher Temps = lower CPU Lifespan = lower obtainable OC = higher cost HSF to keep it stable.

Example vCore of 1.45v for 4.5GHz vs vCore of 1.35v for 4.5GHz, may not sound like much but +0.10v is a lot. The vCore's I posted are averages from MANY examples of both ASRock Z68 Extreme3 vs ASUS 12 Phase models.

The ASUS you linked me to says:

"Ultimate Graphics Power with 3-Way/2-Way Geforce SLI and Quad Quadro cards on demand"

But gives no mention of AMD/Crossfire. Now I know it has x2 x16 PCI slots but would it support crossfire?

CF (Crossfire) isn't a BIOS Key limited technology so I don't know which MOBO you are referring to??!! Example the ASUS P8P67 WS REVOLUTION supports 1~4-WAY CF GPU's; see -> http://www.asus.com/Motherboards/Intel_Socket_1155/P8P6...

Supports NVIDIA® 3-Way SLI™ Technology
Supports NVIDIA® SLI™ Technology
Supports AMD Quad-GPU CrossFireX™ Technology
Supports AMD CrossFireX™ Technology

ALL current MOBO with SLI/CF are limited to (4) GPU Cores, that means GPU's with 2 cores are limited to 2-WAY (2 * 2 = 4 cores). You can easily run 2-WAY, 3-WAY or even 4-WAY CF (crossfire); GPU cores and GPU limits apply.

Ah my bad, I was looking at the tech info from newegg and not the asus website. Cheers for the help, one last thing though.

Would my case be able to hold the ASUS revolution one you recommended? I don't have a picture or a model name (It's unbranded) but I do have the current motherboard type if it helps.

I currently have GA-EP43T-UD3L Gigabyte Motherboard:

It's not a big case I can tell ya that much

GA-EP43T-UD3L ; Form Factor = ATX
ASUS P8P67 WS REVOLUTION ; Form Factor = ATX

Same sized MOBO's :) 

The only issue is IF your CASE has enough PCIe slots. However, for 2-WAY CF I doubt it's a problem.

If I could give you 'best answer' on all your replies, I would

Thanks a lot everyone :)
