LGA 1155 Xeon model
LGA 1155 Xeon model
You're considering a CPU upgrade for your Intel DQ670W board. It's important to verify both compatibility and the right components. Since your current setup includes DDR3, an i3 2120, and a GTX 650, you'll want to ensure the new CPU matches your motherboard's socket type (likely LGA 1151). Also, check if the newer Xeon models support ECC memory for stability. Ecc RAM is typically required only if you need advanced error correction, which isn't usually necessary for everyday tasks like Premiere Pro or Photoshop.
You can obtain Xeons without needing ECC, but I suggest checking out the 2600K for extra security. They really lost a lot of value when the Ryzen lineup changed.
The list of compatible CPUs for that motherboard is straightforward to locate.
