Upgrading from an i7 920 (5450 / 5820k / 6700k)

My 920 setup is in desperate need of some more RAM and a couple of 6Gbps SATA ports, so after a good 6 years it's finally upgrade time (though to be honest, speed wise this thing remains utterly perfect).

Mostly my usage is pretty minor, I write books in my spare time and program for a living (including on this PC), do some minor virtualisation related tasks for work and do light gaming (I have a 970 for that). I do video editing but only 1-2 times per year for a couple weeks tops, one of such times is now, thus the upgrade. I have a brand new 1TB Samsung Evo so no need for an upgrade there.

The three options I see are:

1. Buy more RAM and change the motherboard (& possibly get a Xeon 5650)
The cheapest option is to pick up an X58 motherboard with 6Gbps ports and buy some extra RAM. For a CPU upgrade I could also pick up a Xeon 5650 as recommended here.

Pros:
- Cheap
- Core increase
Cons:
- Not a huge upgrade of technology (remain on triple channel DDR3)
- Second hand parts

Price: £225 - £375



2. Upgrade to an X99/5820k system
An option that would benefit future-proofing and the video editing would be to upgrade to the renowned X99/5820k combo and get 6 cores. This seems like a proper upgrade compared with the other two options, but comes with the associated cost. I'd be getting 32GB quad channel DDR4 with this.

Pros:
- Core increase
- Big upgrade in technology (inc quad channel DDR4)
- Potential for future CPU upgrades to Broadwell-E (though it's unlikely I'd feel the need to do it)
Cons:
- Most expensive option
- Requires overclocking to put its clock speed on par with the 6700k (though I know the difference will be near unnoticeable for my usage)

Price: £650



3. Upgrade to a 6700k Skylake system
The final option (that I can see) is to upgrade to a Skylake system. This would be a fantastic upgrade in technology and cheaper than option #2, but results in me going from one quad core to another, which seems almost pointless (though I realise there's a lot more to it than that). I'd be getting 32GB dual channel DDR4 with this.

Pros:
- Big upgrade in technology
- No overclocking required
- Cheaper than upgrading to an X99 system
Cons:
- No additional cores
- Second most expensive option
- Going from triple channel RAM to dual channel

Cost: £550


Any help would be much appreciated :)

Skylake is dual channel RAM only. Not that it matters at all, triple channel DDR3 is still absolutely fine, as is dual channel tbh.

I had no idea! Amazing what major things you can miss when you're looking into something. Have updated that option, thanks :)

I do of course realise that on a day to day basis dual/triple/quad channel is all the same. I'm mostly interested in terms of its advances in technology (for example, I wouldn't take issue with going from dual channel to dual channel, but going from triple to double kind of irks me).
 
I suppose the first question is why are you "desperate" for 6 Gb/s SATA ports? I'm not sure there are any real-world applications where you'd notice any kind of slowdown using 3 Gb/s ports, especially Intel ones. X58 motherboards are pretty expensive so it might be uneconomical to replace an existing one...although on the other hand you could probably sell your current one for a lot too.

More RAM is understandable but you don't need to run in triple channel mode, so you could go from 6 to 8 GB quite easily by just getting a single 2 GB stick. Or you could jump to 12 GB by getting two 4 GB sticks (and dumping an existing 2 GB stick).

Ensure you're not upgrading just for the sake of it. Personally I see no point upgrading to SATA 6 Gb/s, especially when it's already being made obsolete; SSDs will slowly migrate to M.2 with NVMe support and HDDs barely benefit from 6 Gb/s SATA over 3 Gb/s SATA.

I almost certainly am upgrading for the sake of upgrading, but being in tech that sort of goes with the territory :D I get your point about a lack of need for 6Gbps, I suppose really I just see a use for it given my current SSD is bottlenecked by 3Gbps. For video editing I imagine the increased speed would be useful.

Buy a xeon and a sata3 controller card, doesn't sound like you need much more.

Agreed, I don't need much more, it's more about wanting :D I don't anticipate upgrading again in the next 4-6 years.

5820k all day long, at 4,5ghz km getting 1306 on cinebench same as 2x x5650 xeno 12 core 24 threads

But given the price, do you think it would be worth it vs (for example) a Skylake build?


Thanks for all the input so far guys :)!
 
x58 does not support 6gbps, so any board that supports 6gbps just has an additional controller on.

Meaning it's no different than just adding a PCIe 6gbps controller....
 
5820k, was choosing between the 6700k and 5820k and chose the 5820k due to the extra cores and 'future-proofing' :p
I spout this a lot, but a lot of people are in this boat, so I may aswell help as much as I can by offering advice on what I went with!

And if I might ask, how did you stomach the circa £650 (or whatever you paid) price tag for what is realistically a minimal upgrade (albeit with a big leap in technology)? I need some convincing :D

This!

I had to choose between X99 and Skylake recently granted my previous machine was a way out of date(Q6600) but I went with X99 i7 5820k. No regrets pretty happy sitting at 4.5GHZ.

If it was between 6700k and X99. I'd pick 5820k personally extra Cores :D and it's cheaper at the moment. :p
 
if you can hold out for a few months Broadwell-E will most likely be released.... don't expect it to be that much of an improvement over Haswell-E unless you have the cash flow and the workload to suit the new 10 core..... (they with both work on X99 boards) If you want to go new and save a few pennies now for little loss go for the 6600k with Z170... you could always buy a hyper threaded (HT) I7 Kabylake CPU as an upgrade down the line and save yourself about £120+ now to boot

6600K - £200

6700K - £336

https://www.overclockers.co.uk/inte...ocket-lga1151-processor-retail-cp-581-in.html

As stated by 8Pack if you need HT get X99................

If u need HT u need x99. U don't need HT buy i5 z170.
