Top choice for refurbishing a backup gaming machine is the best Gen 3 Intel CPU.
Hello everyone, the main issue with my older setup is the processor. I'm not very experienced choosing ones, but a third-gen Xeon seems okay if it supports the 1155 socket. I'm going for a new build soon, so this is just a temporary fix. Any advice on the best processor to fit my old machine?
The E3 Xeons are essentially similar to their i5/i7 versions, featuring a minor clock improvement and ECC RAM support. On Sandy Bridge and Ivy Bridge platforms, performance gains become noticeable starting from 1356 cores and 2011 cores. Check the CPU compatibility on your motherboard's list on eBay. Honestly, upgrading seems unnecessary right now given current prices, especially if you're mainly interested in Hyperthreading benefits. If you manage to get an i7 3770k for $20, consider it; otherwise, keep your i5 and plan a platform upgrade later.
Search for an affordable 26/2700k or 3770k unit targeting at least 4.8g OC. Only this will work on older systems.
Beyond price and efficiency, the choice of socket isn't the only factor. It depends on the chipset capabilities and whether the manufacturer has officially certified the board for that specific setup. A processor fitting a socket doesn’t guarantee the BIOS will recognize or function properly. For instance, I refurbished a Lenovo M71E designed for web and media use. It originally had an i3-2100 on LGA1155, but its specs show an H61 chipset compatible only with i7-2600. Even though a B75 board supports the 3770(K), it wasn’t available. Thus, the board’s chipset is more important than just the processor type in that socket. Edited July 12, 2022 by An0maly_76 Updated, more info
3770K seems like a strong choice unless your device uses a 2011 connector, in which case a 3930K would work.
This was another point to consider—whether there’s a significant benefit to an i7 3770k. The cooling and high fan speeds are bothering me with my current chip. Perhaps adjusting the case or cooling setup could be a better direction. Ideally, I’d want this machine to match a mid-tier gaming PC from 2017. Since my processor runs hot without any cooling, that might be a good angle to explore. Upgrading the case or cooling system feels like a reasonable bet, even though it’s not rated for 4th or 5th generation chips. I’m curious how often people take that kind of risk.
It's not only about the board being outdated; the socket design for Haswell (LGA1150) has changed, and it doesn't work with other systems.
