New motherboard and processor for my Dell?

[anastasia17]

Hello I need to upgrade my pc but have some problems. I don't know if the things I want will work on my pc. I have a Dell computer and want a new cpu (i5 4690k socket 1150 LGA ) but it's not compatible with my motherboard (model oc2kjt socket 1156 LGA). So I thought to buy a new motherboard. I found a cheap one (gigabyte h81ims2pv socket 1150). The thing is if I buy this motherboard will it work with all the other things I have in my pc or will I have problems?
My power supply is corsair 450 watt
And graphics card is invidia geforge gtx 760
I'm afraid I'll buy something and it'll turnout to be useless. Please i would really appreciate an advice. And sorry for my English. Thank you in advance

Well it should fit, but a case like that is not designed to let you add standoffs if patterns are different. Also extra standoffs could pose a serious grounding issue. From the pictures that pattern looks the same just shorter.

Personally I would never recommend a motherboard that cheap. It's the center of the computer, everything runs off of it, while it may be fine and work as well as you need it to spending the money on the CPU and throwing it in an entry level board is silly to me. I would rather spend the money on a quality board with probably less headaches in the end.

I will say a budget board is OK for building an auxiliary machine like a HTPC, that's where I put my cheap hardware, non-critical stuff.

So the motherboard is a bad choice right? But I honestly think that the one my Dell system has is no better one. But if I find a better motherboard will it work ok or I'll have problems with the bios

Gigabyte Motherboard H97-HD3 (H97/1150/DDR3 is this motherboard a better option maybe?

The i7-920 is much newer than the Optiplex 755. It is an old Core2 Duo LGA775 machine. Dell has 22A on the 5V rail. Many people have truoble wirh new PSUs which have 18A there. The Legacy BIOS I refer to dates back to the Pentium4 and 65nm Core2 Duo era (Opti 745), The optiplex 755 is just about at the end fo that time since it supports 45nm, and 65nm C2D CPUs. It could be either way. Your I7- 920 is irrelevant to the discussion. It's a newer generation of hardware. There are Optiplex 760, and 780 series that are also older than your i7. So the Opti 755 is MUCH older than the example you give. Were talking about a computer that is one step beyond Pentium4 support.

I seem to be OT here. I apologize. I must have looked up the wrong motherboard from the link provided. Please ignore the above post. Thanks.

Here is a list of motherboards which are compatible with i5 4690k socket 1150 LGA. Choose one according to your specific budget and requirements.

The i5 4690k is a "k" model which has an unlocked multiplier for overclocking. Z97 Express and Z87 Express chipset motherboards are for overclocking. If you are not using those Chipsets, then you might consider using a non "k" CPU.

Gigabyte Motherboard H97-HD3 would be fine with a non"k" CPU as it is not for overclocking. It is ATX Form Factor.
Dell OC2KJT Mainboard Specs

This motherboard is Form Factor Micro-ATX.

GIGABYTE GA-H97M-HD3 is the Form Factor Micro-ATX model.

Dell cases use a single plug for front panel connections and that differs from retail boxed motherboards.
