so i have an old lenovo m58p 6138, with a mtq45mk mobo, and im going to be using the build as a gaming rig with a gtx 460, for light gaming on ark survival evolved, older cods (cod 4/5/6), and im wondering if there is any way of overcloking the cpu, as there is no settings in the bios to do so, and ive tried loads of programs which dont work aswell, im using a 3rd party cooler which is artic brand and i really wish i could overclock it, however, there is no where to do so, if i cant overclock it i will just buy a core 2 quad for the gaming as i might try gta 5 aswell!

You can't increase the clock speed on an original board. The BIOS is set to stop this. GTA V will likely perform poorly on a Core2 system, even with a quad-core processor.

No, you can't increase the clock speed on an OEM board because the BIOS is set to prevent it.

A Core2 model running at 2.8 GHz with four cores might still struggle.

The minimum specs for GTA V are much less demanding than I thought, yet many users mention performance issues. It's time to move on from Core 2 completely—it's been outdated for about seven years. A Skylake i3 will outperform a Core2.

My previous machine was a Q9550 until about a year and a half ago when I upgraded to an FX8350. The Q9550 performs well in terms of Core2. I don't play GTA V, but I remember upgrading from an E6600 to 3.2 to the Q9550 at that speed and noticed a significant improvement on Crysis 3 on a GTX480. It's quite old. Core 2 still works fine for office tasks, HTPCs, and basic PCs, but for serious gaming and pushing performance, as someone mentioned, it's better to go with the Q9650. It supports up to that chip, and if you find one at a low price, it could be worth considering. The main difference is the clock speed is slower, but it has more cores; most games actually do better on single-core performance, which the 8400 offers faster speeds. So, the best option seems to be either matching or upgrading to the Q9650. You might also find it more rewarding to get the Anniversary edition of the Pentium and overclock it.

That Pentium G 3528 was a solid choice, but in reality only having two cores and two threads limits its potential. We have at least one or two moderators who have tried them and they fall short when it comes to gaming. The i3 6100, on the other hand, is a strong option thanks to its high clock speeds and Hyperthreading, which significantly improves gaming performance despite being a dual-core processor.

My previous system was a Q9550 until about a year and a half ago when I upgraded to an FX8350. The Q9550 performs well in terms of Core2. Although I don’t play GTA V, I remember the performance boost from upgrading from an E6600 to 3.2 on a Q9550 at that speed to Crysis 3 on a GTX480. It’s quite old. Core 2 still works fine for office tasks, HTPCs, and basic PCs, but for serious gaming and pushing performance, newer models are better. The new i3 should outperform any Core2 even with an OC.

Now it supports up to a Q9650, and I know used Q9550s are quite affordable. If you can find one at a low price, it might be worth the investment. The trade-off is a slower clock speed but more cores; most games actually benefit from single-core performance, which the 8400 offers better. So, to keep up or improve, the Q9650 seems necessary. You could also consider getting the Anniversary edition of the Pentium and overclocking it instead.

The main issue is that a new i3 and motherboard cost around £150, while a Q9550 is only £40 used. I’m curious if it’s really that bad, since my brother will be using it for games like Ark Survival Evolved, Rust, and checking if GTA would work.
