Upgrading from the 2nd gen doesn’t look worthwhile.

Ivy Bridge Intel Core i7 3700k is the best LGA 1155 CPU, which is way better than the i7 2700k and comes at the same cost. The cores and the threads remain the same, and it also comes with four cores and eight threads and supports Intel Hyper-Threading technology, which offers excellent performance in games and other applications. The things that changed between these processors are a generation gap with more transistors, better clock rates, and performance.

Like the current generation processor, it also got a 100 MHz boost in clock speed from the last generation and provided a base clock of 3.5 GHz. It’s the best 1155 CPU in which turbo reaches up to 3.9 GHz and allows a little bit of overclocking with the stock cooler. While in reviews, we can see that the gaming performance of this processor is good enough, but we can’t expect something like what modern machines are offering us these days.

Overall, when we see it in terms of performance for modern games and applications, there is no doubt that this is the best powerful LGA 1155 CPU and what else we can expect from eight-year-old hardware. One thing to note is that the non-K version is slightly cheaper than the other one, and if you don’t consider overclocking, you are good to go with that one, but you need the K variant for overclocking. Intel Core i7 3770k comes with an Intel HD 4000 series graphics card quite good for mid-level gaming.

The Intel Core i7 2600k was a great edition in the Sandy Bridge processors, and it offers excellent performance for its price which makes it the best LGA 1155 CPU. This processor’s gaming and raw performance are not like the hardware we are getting these days, but still, it manages to give an excellent raw performance. One of the best things to consider for a low budget is its multiplier is factory unlocked, and you can get some extra performance from it.

The semiconductor conductor technology used in this processor is 22nm, where you might already know that AMD is releasing processors and graphics cards of 7nm these days. It’s the best mid-range LGA 1155 CPU that was launched in Q1 of 2011, while the company discontinued it and processed its last batch in Q1 2013. It comes with a base clock of 3.40 GHz while on boost, it can easily hit up to 3.80 GHz, and still, you are allowed to push its clock rates.

One thing that might disappoint some users regarding this processor is its price, but it is worth it for its performance. Also, I found that the performance difference between this processor and i5 2500K is not that much, but it’s way more expensive than that CPU. It’s the best CPU for LGA 1155 that is great for games released before the last two years, but if you consider lowering the resolutions and other in-game settings, you can efficiently run them with this CPU.
