Hey everyone! I'm upgrading my XPS 8940 which currently has an i7 10700K that seems to be on its last legs. I'm looking at getting the i7-14700K from Newegg, which comes bundled with an MSI cooler. However, I'll need a new motherboard since the existing one doesn't support the newer generation CPUs, and unfortunately, that also means a new power supply because the Dell PSU uses proprietary connectors, and the 500W capacity is insufficient for my planned build.
Here's my intended setup:
**Locked in parts:**
- **CPU:** Upgrading from i7 10700K to i7 14700K
- **Cooler:** Swapping out the stock cooler for the MSI MAG CORELIQUID A13 240mm (which comes with the CPU).
- **Memory:** Keeping my current DDR4 RAM.
- **Storage:** Moving my 970 EVO M.2 and 2.5" 870 SSD over.
- **GPU:** Keeping my MSI VENTUS 2X OC GeForce RTX 4070 12 GB.
**Tentative parts:**
- **Motherboard:** Considering the MSI MAG Z790 TOMAHAWK WIFI DDR4, but I'm flexible if there's a better option.
- **PSU:** Looking at the CORSAIR RM750e to ensure I have enough power.
- **Case:** Maybe a LANCOOL 216 for better airflow, possibly salvaging some fans from the XPS.
**Key requirements for the motherboard:**
I want to keep using my DDR4 RAM and I need at least four USB-A ports plus a way to connect a USB-C expansion card that powers my Oculus Quest 2. If it helps, I'm okay with a PCIe x4 slot available for that card if the motherboard has the needed USB ports already.
So, what do you all think? Does this build sound solid? Is the Tomahawk DDR4 the best choice for my needs, or is there a better option out there?

That sounds like a solid plan! Also, check out this motherboard; it might save you some cash: [MSI Pro B760](https://pcpartpicker.com/product/yMGbt6/msi-pro-b760-p-wifi-ddr4-atx-lga1700-motherboard-pro-b760-p-wifi-ddr4). It has what you need on paper and is potentially cheaper than the Tomahawk!
The Tomahawk is definitely a great mid-tier option. Just keep in mind that it’s designed for 12th-gen, and we’re already progressing to 16th-gen now, so consider how that might affect future support or upgrades. You'll also see a performance difference using DDR4 instead of DDR5, especially since DDR5 can be overclocked substantially for better performance.
I see you're only keeping the RAM and GPU, right? Might want to create a PCPartPicker list for your new components; it makes it easier to visualize everything.
Good idea! Here's my list: [PC Part Picker](https://pcpartpicker.com/list/mZHXwY).
That's good to know! I don't really overclock, so is the DDR5 upgrade worth it for the price? How significant is the performance difference between the two?
