Input needed on a few motherboard choices please

[soulweeper]

I'm building my first computer, and I have the Corsair 500R case, and I have the Corsair 650HX PSU, FWIW. I'm going with the i5-2500 CPU

I'm not a gamer, don't use any intense programs, but don't mind going a little overkill and just building a nice computer.

That being said, I'm considering these three

The first and third one are ATX, the middle one is Micro ATX...not sure how much difference and how much better one is over the other. A friend said the ATX will give me a little more room to work on. The first and third one also have onboard USB 3.0, which doesn't necessarily seal the deal, just that my case has front USB 3.0 ports, so pointing that out. The other obvious difference is the chipsets, but from what I read, the Z68 has a couple features I'd probably never even use, over the P67, but it wouldn't hurt anythung going with that chipset either.

With my limited knowledge, it seems like I could go with any of these, the first one being my first choice, but I'm brand new to this building thing, so any input on the pros and/or cons to any of these would be appreciated. Thanks in advance!

Go with the first; it's cheaper. The z68 is recommended for Ivy bridge if you want to change cpus later. I also like having onboard video for backup.

Thanks for the reply!

I guess I should add that I am using a GeForce 550ti GPU, but yeah, I wondered about the onboard video being a benefit too.That being said, I can get the second one at Amazon for $15 less, and still get the $20 rebate, no tax, no shipping, but it is a Micro ATX., and doesn't have onboard USB 3.0

I still feel like the first one is the way to go, even with that, do you agree?

Yeah, you may want usb 3.0 eventually; I haven't used any devices with it yet.

I ended up ordering that one. Seemed like the way to go. Thanks for your input!
