If I upgrade my CPU will I need to change my mother board?

I'm slightly new to computers but the past few months I've been getting ready to upgrade my gaming PC during christmas.

So far I have :
Radeon HD 6800
Intel Intel Core i5-650 3.2GHz ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... )
ASUS P7P55 LX LGA 1156 (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
- 530W power supply

I'll be upgrading to:
- Storm Stryker Case
-Radeon 7950 Vapor X

And I've been thinking about changing my CPU to a Intel Core i7-2600K Sandy Bridge 3.4GHz.

If I did , would I have to buy a new mother board?
My current one supports : Intel Turbo Boost Technology" But the new CPU is " Intel Turbo Boost Technology 2.0 " I'm unsure if those are different things.

If yes to upgrading, could someone please link me to suggestions?

Or, if the CPU upgrade isn't that big of a deal please tell me. Saving money would be useful but hey, it's christmas.

Thanks in advanced !

I believe so.

The 2600k is socket LGA 1155. http://ark.intel.com/products/52214/ whereas your motherboard is 1156.

Unless you're seeing poor performance I see no reason to upgrade from that CPU which seems perfectly capable.

Yes, you would need to upgrade your motherboard. The i7-2600k is an LGA 1155 socket chip; your mobo is LGA 1156 and the two are not compatible.

The Asus P8Z77-V Pro is a good LGA 1155 mobo. ASRock Z77 Extreme 4 is a cheaper but still good option.

Yes. Why that specific cpu though? Unless you can find that cpu for cheap, i'd suggest going for ivy / haswell (better stock performance).

Or you could go for the AMD route which is slightly cheaper and you could get a R9 280X instead.

I currently have an intel and saw a suggestion about the i7. I've never tried any of the other brands, so would you mind telling me the differences between let's say a intel and AMD?

AMD CPUs are generally cheaper and have worse single-threaded performance than their intel counterparts, but their 8-core models (FX-8xxx) have better multithreaded performance than quad-core i7s. For gaming, however, it is generally accepted that intel CPUs perform better than AMD because games rely more on single-threaded performance and do not scale well above four cores.

And of course they use different sockets and motherboards than intel chips, so you will still need to change mobos with a new AMD chip.

Ah thank you. So it seems intel is the way to go.
I've noticed there are many versions of the i7. Very confusing to me, lol. If I did decide to purchase a i7, I'm not sure which one I would choose. The one factor I'd put in is the small amount of money I could save. I see some as 290$ but I don't know if those are decent or not. Must atleast be better than my i5, but would it be a huge difference?

I'm also seeing a lot of reviews saying the stock heat sink sucks. I'm guessing I'd have to replace it if I plan on OC. (Which I don't).

since you're not overclocking there's no need for a "K" cpu. As well as go for B85 motherboards.


This brings to my previous question. Will it be a huge upgrade from my current i5 or not? If it isn't than I guess there;s no point in upgrading.

I think you should try your current CPU and if it is holding you back THEN upgrade. I doubt it would be necessary to get a new one.

Dumb question but is there a proper way to tell?
I just tried playing a game of TF2 and my CPU on task manager gets to 70%. Not sure if that's good or bad.

If it matters, I'm unable to livestream games due to cpu usage getting to 100%. (Procaster/livestream). Start up takes a while. There has been a bit of lag lately in photoshop or any intense program. (Understandable.)

Due to my card I mainly play games on Medium settings.

What kind of FPS do you get? Sounds like your GPU is bottlenecking your CPU currently. Fair enough about the live-streaming situation, many CPU's struggle. If you're looking to do that often then an upgrade may be necessary.

I'd still wait and get the GPU first, and then if you have a CPU bottleneck then upgrade to a better CPU.

Livestreaming is something I'm interested in (as well as recording) but not something I absolutely need.

I'll try again around christmas time, aka, the time I get my new gpu.

Alright, nice. If you feel the question has been solved it would be cool if you could pick a best solution. :)
