I7 with GTX 680 or i5 with GTX 670?

[EDIT] The thread title is wrong and I don't know how to change it. Obviously I mean i7 w/ GTX 670 or i5 w/ GTX 680.

I'm in the process of buying a custom build pc for gaming. I was wondering what would be the better option, with price in mind. I have the rest of the configuration sorted and now just need to decide whether to get an i5-3570k with a GTX 680 or an i7-3770k with a GTX 670. the former option is £35 more expensive. (neither processor is overclocked)

Is the 680 worth the price difference over the 670? As far as I can tell from various comparisons it only benefits from a small increase in performance, around 5%. Having said that an i7 isn't necessary for gaming, so an i5 with 670 is also an option and would save me about £100.
Thoughts?

More about : gtx 680 gtx 670

Hello buddy, the GPU decision is more than obvious, GTX 680 = more performance but the problem is.... how much performance will you get for the extra 100$??

take a look at this:

http://www.anandtech.com/bench/Product/555?vs=598







The overclock is 1100 on the core and 1760 on the memory.




Now...the CPU decision.

The i7 and i5 Perform exactly the same in every game, and if you turn the HT in the i7 your game performance will be reduced but your rendering/editing/transcoding/decoding/encoding/hashing/general performance will increase by about 20-35% (in some cases 50%) over the i5, this happens because games can not handle well more than 4 cores (some can only handle 2) making the extra virtual cores created by Hyper threading useless, if you want a deep explanation of this phenomenon let me know but i don't think you do, lol!


August 17, 2012 9:31:28 PM

If I were you I'd save about £100 and get an i5 with 670.

I say i5 and ASUS 670 GTX (yes, I know you meant to edit your title). I suggest this because, for gaming, i5 vs i7 is no different for the explanation given above. The charts shown above are of a stock 670 (I believe), but the ASUS 670 GTX DC2 is basically as powerful as the 680 GTX so you'd be saving $80 you could spend on a better MoBo (if you are about to build a computer instead of upgrading what you have).

I don't see why spend close to $500 on a video card that offers no new things. I'd justify spending $500+ when DirectX 12 cards start shipping.

i5 w/GTX 670

get a nice MSI OC board that will let you push the 670 to its true potential

i understand ur title edit, its just not worth the extra $$$

I'm using pcspecialist to build my spec and they offer the stock GPUs I believe, so I would have to buy that separately and do it myself, which is probably very easy but I'm not confident and have no experience with building or fitting anything!

I suggest you get an ASUS ROG Motherboard and an i5 3570K (k means unlocked for overclock). That intel chip comes with Intel HD Graphics so basically, the computer would work without a video card because the intel chip gives you a crappy one.

Use PCspecialist website and just not include a video card, then get the asus 670 elsewhere and just slide in, connect the 2 power connectors and thats it.

The "hard" part is wiring chassis fans and power buttons and front USB ports etc which you wont need to do by ordering from them with no video card. It is really easy no way you can mess it up.

Building a PC is extremely easy and even a blind person can do it, there billions of guides on the internet, i can link you a few if you want.

Simple explanation:

Hyper threading emulates two logical core per each physical core. if you have 1 Physical core and you enable hyper threading you will have two logical cores, the 3770k has four physical/logical cores and when you enable hyper threading those 4 cores emulate 8 cores, the result?? better usage of the calculation units
August 17, 2012 10:16:52 PM

I literally have *no* experience whatsoever with anything like this, you're talking to a person who finds a screwdriver difficult to use. It would be a pretty big undertaking and I would gladly pay the extra money to get the computer built for me.

and better usage of calculation units means... better performance? Sorry I'm a bit of an amateur when it comes to this stuff

You might be right but after you build this PC you will have the necessary knowledge to take apart and reasamble almost any PC in the world!!!

besides...even a retarded person can build a PC, is a LOT easier than what you think!! let me know if you want a few guides

Edit: i know its a bit scary doing something new when you know for sure you suck at it but until a few months ago i was afraid of water cooling my PC but i decided to buy everything i needed and guess who has 4 GTX 680s/i7 3960x/Asus Rampage IV water cooled with no leaks??? and i did it in barely 1 hour

Yes, emulating the extra cores makes the OS think that you have an 8 core CPU, that allow the OS to use more threads... that means better performance, but not in games.

Thanks for your reply. So when does hyper-threading come into play? Does it only start when many CPU intensive applications are running at once or is it all there constantly (as I imagine that would increase power consumption + heat)

it doesn't increase power consumption but it reduces the overclocking potential.

HT comes into play when you use applications like Maya, Mathlab, CAD, Adobe suites, HEAVY rendering, etc.

Thanks for the encouragement and reassurance but I am set on using pcspecialist, or a similar design-your-pc site. Perhaps I will realise what a "mistake" I've made in a year or so when I realise how easy building it yourself actually is! But my budget has been aimed at a particular pc and now I have the money I don't really want to concentrate on anything else. Besides I am pretty sure it will keep me happy for quite a while and will be able to play all current and near-future games at high or max at good fps. If I change my mind I'll let you know though!

Also that rig is just unbelievable! What in all that is holy do you run that needs all that?! You must play at 20,000x15,000 resolution ha!

Here's an example -

That may be kind of confusing, but Hyperthreading is always on. At idle, my processes aren't using much CPU power, so Hyperthreading will also be in it's 'off' state. It's only using the cores without Hyperthreading.

When I open a program that is HEAVILY CPU bound, it will utilise almost all of the threads like this -

August 17, 2012 11:15:58 PM

Seems as if most people think going for the i5 with 670 is the best option. If so what do you think the saved £100 should go into?

Firstly, if you are looking for a stable 4.2+ overclock, you shouldn't even go Ivy Bridge. Just go 2500k.

Between the two, I'd say go i7 with 670. For one, I think people here have touched on the fact that the 680 isn't that much better, but also, the i7 would do you much better in terms of future-proofing. Sure, there are still some apps out there that aren't written to optimize Hyper-threading potential, but a year or so down the line, that number will definitely increase and It would be much better to have an i7 CPU you wouldn't have to risk OCing instead of a 3570k we would have to OC to remove bottleneck. There are some games out there that benefit from the extra CPU horsepower, obviously (Starcraft, GTA and SHOGUN come to mind), so it's not like the extra muscle would go un-used. Now, obviously there are some drawbacks to HT, like temperature, but that wouldn't really matter if the app itself isn't written to hyper-thread, correct me if I'm wrong.

Overall, If you're looking to OC, I'd say go 2500k and pick up a Hyper 212, but if you really want to stay within the confines of Ivy, go i7 670

Wow :o 

Just to get it on the record were you in favour of the i5 w/670 option too? Also is there hyper-threading on the i5 at all?

What are you talking about?

*Ivy bridge can be overclocked to 4.8-5Ghz using a decent closed loop WCer

*There is no such thing as "Future Proofing" only overspending.

*The games you mentioned can be run with a 128MB AGP video card.

Thanks for your reply. I'm not overclocking but I'm still getting the unlocked CPU just in case I want to in the future (doubt it though but it's only about £15 extra). How would games, for instance the ones you mentioned, benefit from an i7 over an i5? I was under the impression that games were almost entirely GPU dependant?

Is an i7 while the HT is idle hotter (and the fans louder), than an i5? I don't want the fans going crazy while I'm not doing anything CPU intensive.
August 17, 2012 11:43:19 PM

^ He may be talking about the most recent games, however, I do agree about Overspending and the IB OC.

If you're lucky, you can OC a 3770k up to 4.8Ghz using an air cooler.

Also, Civilisation V (I understand this may not be the best example) only uses 50% of my i7, hardly worth the cost compared to an i5. I bet I would be getting the same frame rates on an i5 for this title.

An i7 would only be worth the money if you can get it at a decent price IMO. And I'm talking within a few $ of an i5.

At idle, the temperatures are almost within margin of error, very similar. (I've turned HT off on my i7 just to experiment).

Under load @ 4.8Ghz using 1.39v, my 2700k with HT ON has an average temperature of 77C. With HT OFF at the same settings, I get an average of 65C (All cooled by a Hyper 212+). The fans don't get too loud IMO if you use an after market cooler. If you're using stock, it may be a little on the loud side, however.

As you can see gaming performance is reduced when HT is ON.

In the benchmarks you see that the i7 rapes the i5 (FPUSinjulia, CPU queen,etc) are EXTREMELY optimized for multiple threads and it DOES NOT reflect real world performance, the gaming benchmarks are based on REAL WORLD performance.

Before you get into a Sandy vs Ivy argument let me just say I'm not overclocking! Doesn't really benefit gaming and I don't want to spend more on some liquid cooling and a big PSU etc.

Yeah I see where you're coming from, this i7 is nearly £100 more and considering I'll mainly be gaming and running not hugely CPU intensive apps I don't think I need it. (out of interest how demanding are DAWs like FL Studio, Logic, Ableton etc? I use those a fair amount).

*Overclocking doesn't requiere liquid cooler or big PSUs, lol!

*You can easily mix/edit/whatever to music with a Pentium 4 :lol: 

*Overclocking a CPU might increase gaming performance by much but overclocking your GPU does!

That's interesting. Looks like the i5 for me then. But I thought OC'ing didn't make much of a difference when it comes to gaming?

Can't comment on that....@5760x1080 everything is different :lol:  when my i7 3960x is running @5Ghz my frame rate increases by almost 15fps! (although i think that happens because of a small bottleneck in my system)

But it is recommended to get better cooling when overclocking, liquid not necessary but certainly helps.

So if I were to overclock, what changes would you make to accomodate an overclocked 3570k-for instance?

Actually on a serious note, I'm not sure if people really DO argue about that. I know there have been some talks about Ivy's temperature problems and some possible theories, but not a direct head to head argument :lol: 
August 18, 2012 12:03:48 AM

I would personally get something like a Hyper 212 EVO. They're a very modest budget-friendly cooler that performs great.

August 18, 2012 12:17:29 AM

Well with the money saved by not getting a 680 I could overclock the i5-3570k and get some fancy liquid cooling, good idea or waste of money?
August 18, 2012 12:20:45 AM

Closed loop coolers (I'm generally against them) actually perform pretty well. I'm not sure how much they would charge for a fully custom loop though..that's if they even do that.
