I've been using Gigabyte motherboards for about 8 years now and have found them to be very reliable indeed.

Here is a selection of Gigabyte Z77 LGA1155 socket boards for you to compare.  The GA-Z77X-UD5H looks quite impressive and is packed with features, but I'm sure any one of the selection would more than adequately suit your needs.

Hope this helps.

I just got a UD4H on sale at Tiger Direct for real cheap. It was the best deal I could find. I think it was around 120.00 USD.

I have been upgrading my gaming rig two or three weeks ago with Core i5 3570K and Gigabyte 670GTX with 4GB RAM (for large texture pool games like Arma 2), and I had to chose a new board as well. 

I bought the GigaByte Z77-D3H, and let me tell you, it was awful-to-horrible. The BIOS was a mess, the whole board system was unstable on stock clock values of the components - RAM errors, blue screens, restarts. It was the 1.0 rev though, 1.1 has larger secondary PSU connector (8 pin instead of 4 pin), so power stability might be an issue, but I have returned the board to the vendor. 

I replaced it with Asrock Extreme 4, and it's much better - the BIOS is very nice, the system rock stable, the overclocking options much more logical and consistent.

Having problems with Gigabyte 8800 GT in the past (revision with bad memory, some games did not run at all), I am not that impressed with Gigabyte Hardware. Asus may be a better choice overall.

Just one word of warning I learned the hard way - the new chipsets boot to UEFI by default, and it is probably wise to install the new OS on UEFI an partition, since the good old BIOS is being phased out. There is a nasty bug in Windows 7 64bit that causes the boot sequence to hang if you have a SINGLE hard disk connected that is still MBR (not GPT) containing an extended partition with logical partitions. What I had to do was to install on a clean GPT formatted disk, then backup all my important files, reformat all the old disks from MBR to GPT (the disk must be empty to do so), and move the data back from the storage. I spent two days with this tedious cleanup, so BEWARE!

@Kamamura i doubt that ! GigaByte Z77-D3H /Chipset: Intel® Z77 Express -factor: ATX 2x PCIe x16, onboard, CrossFireX

• You blame it on the board / seriously buying almost the cheapest board with crossfire support and having a 670GTX? 
   ok you only have one gfx card so it doesnt matter but still 
  
  
  @Anthony before you go and buy :
  How long do you want to use that new computer...
  Do you want to be able to upgrade
  What graphic card are you planning to get...important
  
  Make sure to invest most of the available money on PSU and MB and not into a fancy dandy GFX card
  
  The PSU and the Board are equally important like the CPU itself.
  A list list of mainboard manufactures i trust in.
  ASUS, Gigabyte, Intel, (asrock) 
  the gigabyte version for that chipset GA-Z77X-UD3H ( crossfire ) or Gigabyte GA-Z77X-UP5 TH ( card doesnt matter )
  ASUS Maximus V Gene  might be Ramapage available by now dunno
  Intel DZ77GA-70K
  
   

Your logic has received a serious bump in the head somewhere on the way. The board had every feature I wanted, the reviews I encountered mentioned no problems for the 1.1 rev. I did not even know the supplier would deliver the old 1.0, maybe the 1.1 would be without problems. Since crossfire is irrelevant, I don't know why you even mention it.

Contrary to your advise, I would not spend heaploads of money on the boards, especially if you don't overclock, because all the extra price often goes to features like fine voltage setting for OC or extra ports you won't need anyway. 

A cheap board that is stable and does not have cheap condensers that will leak under heat is often quite okay, since the performance differences are minimal. I had numerous cheap boards in the past with no problems. 

If you conserve your funds, you can get more performance from the memory/CPU/GPU configuration, and more performance also means greater longevity.

A stable, well-manufactured PSU, on the other hand, is a good investment. PSU lasts longer, due to chipset changes you have to throw out the old MOBO with each CPU upgrade anyway.

Sorry Kamamura no need to be angry i just have to laugh when i see folks getting a crossfire ready board and they stick a Nvidia GFX on it sure your 670 will hold and work  but what if you need to upgrade, if its not enough anymore or want to go for SLI ? Not an option ? in this case probably not.
Unless you have 2 spare radeon cards

I prefer , to be able to upgrade a good board, without investing 2x400 USD in another GFX card bc i choose the worng card setup on the Mboard,
in this case a radeon setup is possible.
But will you buy 2 new readeon cards if the 670 doesnt fullfill the job anymore ?
Or the next step buying a new GFX card that is currently close to 1k,  the 670 is already running on the edge.
But would it be logic to get 2 new GFX cards instead of buying one that you could use parallel with the current card ?
I just dont understand, if you had the 670 spare or bought that card new why didnt you buy a SLI board instead of the crossfire ? or SLI and crossfire compatible board.
I just dont see how it is wise or more logic to end up possibly spending 400+ usd on a GFX update or close to 1k instead, if you want to replace the 670 or if your planning to go crossfire there is no way around than buying 2 readon cards close to that price instead of getting the GFX or MB that will fit your need + an option for a GFX based upgrade later on instead.
i dont see the logic to not make an investment of round about 50-100 USD more on a good Board that would fullfill these needs in a long term compared to an upgrade that is (limited) and will cost you about the tripple or four times the money. 

I have an MSI 970A-G46 and it has a UEFI Bios. Comes with an app that allows access to the bios from inside Windows too!!

I hear good things about MSI.

Thanks for the recommendations. Ive thought about getting a board with thunderbolt support in case I needed it, but I've read lots of complaints with people saying its not quite ready for prime time. any experiences with it?

Yes but i dont have one at my Home pc, The technologie itself is still on new ground ( PC ) but we have 2 chained at work.
The thing is that the upgrade for a new board and the thunderbolt drive itself is still quite expansive and have the standpoint of a freshly released ssd what doesnt make it worth ( at least for myself atm ) while i do plan on upgrading my board as sson as the prices drop a little.
So i would say if you got the money it doesnt hurt to invest in a board that supports it. 

Alright, I pulled the trigger on it and went with Gigabyte after all...

Should scream with an i7 3770k

Hey Anthony, nice choice.   Coupled with the 3770k you should be quite happy with that mobo choice an enjoy many years of speedy and reliable computing.

I got the case today. The Fractal design Define R4 with side view panel. they overnighted it even though I didn't select that option. Its like the Sherman tank and Rolls Royce of computer cases. What a beast.

With this board I was thinking of setting up a dual boot 'hackintosh' and win7 setup.

Which color did you take? I would go white, it looks like a refrigerator, heh

Anyway, very good choice, i have R2 at home myself and chose R4 for a new computer at work. Love the sharp edges and overall minimalistic design, better looking than Lian Li stuff IMHO. And that is quite a feat. 

I got the Black Pearl.. its really the nicest case I've ever seen. Most cases from Corsair, Roswell, and Antec look like Mattel toys for kids. The Fractal Design is built for a real rig.
