Fastest LGA 1155 CPU!

[AstroMagic]

I want to know what is the fastest and best LGA 1155 cpu that's available out there on amazon newegg etc. i will keep this CPU for a future reference and as well as ask this question in about 6 months because i know for sure the answers will be way different but i may just get one now.
I also have a oldish pretty good i3 2120.

i7 2700K

As one said the I7 2700k but at 349, probably NOT worth it. Look up cpu benchmarks to compare cpus.

The answer now will not change in a few months. The LGA 1155 socket is a dead end socket meaning that there aren't going to be any more products made for the platform. The fastest CPU for 1155 is the i7-3770K. But depending on what you're using your computer for, it might be a better option for you to go with the i5-3570K and it performs almost as well as the i7 in not so multi threaded applications.

What about fastest duel-core?

i3-3250

*It's not much faster than what you already have now though.. it scores 4429 and yours scores 3870 in Passmark.

The reason it's not much faster is that it's only 200Mhz higher frequency and one generation newer but otherwise but have two cores which are hyperthreaded.

*It's worth noting that the i5-3330 is a 4-core (4C/4T) CPU of the same generation (3rd) but only runs at 3.2GHz. Thus it's almost 10% slower than the i3-3250 for clock frequency. In some cases an i3-3250 might match or even beat it!!

**I see no point in upgrading unless you get an i5-3570 or i5-3570K ("K" for Z77 motherboards)

4th gen (HASWELL) is 10% better at the same frequency as 3rd gen (i.e. 4.4GHz on 3rd is same as 4GHz on 4th). I recommend just keeping your system and upgrade to an i5-3570 or i5-3570K because otherwise you need a new motherboard and unless you have Windows 8 you likely need to buy a new copy of Windows as well (W8 OEM you buy yourself is transferable but W7 OEM is not).

Thus it's about $210 for an i5-3570, but to upgrade to 4th gen if you need W8.1 and a motherboard might cost $450+.

Depending how windows 10 goes i will buy that and just build my self a $500 computer or just simply buy windows 10 and get my slef a new motherboard compatible with all the items i have now except the CPU so in about a year or so right before or after 2016 CES to see and wait for cheap great motherboards and 4k monitors.

I just wanted to point out that most LGA1155 motherboards can accept an Ivy Bridge cpu with a bios upgrade... several of the answers were claiming that the 2700k (sandy bridge) was the best cpu for LGA1155. Others rightfully noted that Ivy Bridge can work, if your mobo can be upgraded to accept an Ivy Bridge cpu.

Here's my question: The main thing I need speed for is video encoding (x264/handbrake) of my DVDs and Blu-rays. I currently have an i5-2500, and am looking for the fastest cpu to carry my z68/lga1155 mobo through the next few years. Obviously the i7-3770k is the top cpu for this mobo, but will it make much of a difference for video encoding between the 3770k and the rest (3770, 3570, 3550, 3250, etc.)? I don't overclock, so don't care about the "K" designation, unless it means more stock speed and/or better video encoding.
Depending on the encode, I sometimes use QSV and sometimes don't (QSV is decent but if I want best quality I don't use it).
Any advice/tips/suggestions/etc. greatly appreciated!

I'm using a Xeon E3-1280v2 in an 1155 Z77 motherboard and 16GB of ram. Although the mobo can be used to overclock if I purchased an i5k / i7k CPU there is really no need as I use the rig for 3DS Max 2015 & Vray 3.0 rendering.

I was lucky. I picked up the Xeon for a mere £200 new from eBay. These CPU's are still going for over £500+
The rig breezes through all my work with ease. (Be aware not all these Xeons have integrated graphics)
As I also don't need a Quadro GPU I opted for one of the latest GTX gpu's with Maxwell architecture and saved quite a bit of money.

The last rig I used for rendering was an HP ML110G6 server with a Xeon X3450 (4cores / 8 threads) and 16GB of RAM. Picked it up for buttons and it was a fast rock solid machine.
