Looking for a better LGA 1155 motherboard

Hey guys,

Currently I have the ASUS P8Z68-V. It's a great motherboard for what it was designed for, and hasn't ever given me a single problem. When I first bought it, I wanted something basic, but great and reliable for its price. And that's what I got. But now, about 1 and a half years from when I built my pc, my needs have changed and I need something a bit better than this. I'm currently running a 7970 on the top PCI-E slot and a Sound Blaster ZX sound card on the bottom one, and there's barely enough room to fit another card in there.

It's fine with it's current usage, but very soon I'm upgrading my 7970 to a 780 and the ZX to a ZXR (bigger, better sound card, although I won't be using it's daughter board). Also, down the road I plan on grabbing a second 780 for SLI. I do plan on overclocking my 780 quite a bit (this is my first card I'm ever going to try seriously overclocking).

So not only would I not have enough room, I'm afraid I would run out of bandwidth with PCI-E 2.0. I have decided then that it's time to upgrade. So can you please give me some suggestions or recommendations? I really like ASUS, don't know much about the reliability of the other brands, (a friend recommended to me the Gigabyte Sniper and one of the MSI boards). If I get another ASUS will I still have to do a fresh reinstall of the OS?

I also have a few questions.

1.) Is there any reason to get a Z68 or a P67 over a Z77?

2.) I realize I won't be able to take advantage of PCI-E 3.0 with my i5 2500k. So with any motherboard upgrade I'll be getting the same bus bandwidth as I'm currently getting with my Z68?

3.) For my uses, is PCI-E 3.0 needed or would make a good difference? I would really hate spending even more money on a new CPU. From what I know, from a performance standpoint there really is no reason to upgrade to Ivy Bridge or Haswell from an i5 2500k. Mine is OC'ed to 4.5 and never gets above 70C in any game, it's great. So is my bandwidth is going to be really tight with 2 (eventually 3) devices using my PCI-E lanes, making PCI-E 3.0 worth the upgrade to a new CPU? Besides that, I'm only worried about one other thing with my CPU, which is...

4.) With this new motherboard I'm getting and a 780, is my OC'ed i5 2500k going to be a bottleneck in games?

I really don't think I need or upgrade my CPU, nor do I want to. But if the bus bandwidth is too saturated and/or if the i5 2500k is not enough with a 780, please give me your honest opinion if a CPU is worth the upgrade.

Sorry for deviating from the original question, but they're all related. Thanks so much.

You can move up to the Z77 and still run your 2500K, I've put mine in Z77s with no problem, and then moving up to a stronger GPU will get you the PCI-E3 though you prob won't be able to tell the difference between running it on a Z77 or backward on a P67-Z68
 
I was wondering what case you are using? In the picture it doesn't look like you have any space for a larger motherboard. Can you list you current system including the case.

1. no get the z77, it has many more features
2. If you are talking about having 16 lanes for PCI-E they both do but the 3.0 version is better then the 2.0 version and the card you have the 3.0 version.
3. Yes PCI-E 3.0 is better and your VGA card can take advantage of it.
4. The i5 2500K should be oaky but since its unlocked you can OC it if you start getting a bottleneck.
5. You have time to update the CPU if you want more performance later.

Use this link to have a better idea on the advantages of the Z77 or the Z68 chipsets.

In response to the PCI-E 2.0/3.0 answers, I thought that since my CPU isn't 3.0 compatible, the entire motherboard wouldn't be able to take advantage of 3.0, meaning my 780 with still run like it would on a 2.0 board, and that 2 780's would come close to saturating the bandwidth.


My case is the original NZXT Phantom. Plenty of room.

My specs:
i5 2500k @ 4.5GHz
Cooler Master 212 EVO
ASUS P8Z68-V
16GB Corsair Vengeance Red 1600MHz
Sapphire HD 7970 3GB OC with Boost
Sound Blaster ZX Sound Card
Samsung 830 256GB SSD + Samsung 1TB 7200 rpm
Corsair HX850
LG Optical Drive

I'm looking for a motherboard that is SLI/CFX compatible, and that can handle 2 780's and a ZXR (so 3 PCI-E lanes). Although my system is high end, it isn't ultra high end (still on air, older CPU although still a very good one). So I'd like to find a motherboard like that as well. If possible, I still want my 780 and ZXR to run at x16/x16. This motherboard is x8/x8 if I'm running 2 PCI-E devices. I know that if I get a 2nd 780, I probably won't get x16 for both gpu's and the sound card unless I get a really really high end board. I'm not looking to blow big bucks on an enthusiast grade motherboard, but I need something that has a lot of room, the bandwidth won't get too saturated on, and is reliable as this Asus motherboard is.

Is $200 too low for that? I live near a Microcenter, and they have a lot of clearance sales and heavily reduced motherboards, so I will take a look. Just let me know what to look out for. Thanks!

Hmm they seem to have the same space between lanes, same as my motherboard.



You're referring to PCI-E 2.0/3.0 yes? I knew it wasn't a noticeable difference, I was just making sure PCI-E 2.0 won't be too saturated with 2 780's and a high end sound card.

If I don't have to worry about the lanes getting saturated causing a potential bottleneck or a huge performance difference between PCI-E 2.0 and 3.0, I'm going to wait until I get that 2nd 780 to upgrade my motherboard. Physical space is the only reason I would need to upgrade, but I'm not getting a 2nd card right away so there's no reason to until I do get it in a year or two. By then Haswell's successor or the generation after that will be out, so I'll upgrade my CPU in addition to a new motherboard for that new socket. As long as my CPU or mobo isn't a bottleneck for the 780, I think that's a good decision!
