I5 or i7? (desktop upgrade for gaming)

Hello all!

My name is Przemek, I'm new here.

I wanted to upgrade my desktop. Recently I've come back to gaming (woohoo!! :D ) and what I have is way behind today's standard. I was looking at an Asus P6T SE + an Intel i7, or a differen mobo and an Intel i5. Both quad-core, both 2.66. What is the factual difference between the two? If I take i5 will that have a lot of negative impact on the quality?

Also what else would you recommend that I get new? My videocard is Asus Radeon HD 4850 1 GB (bought like 2 mths ago). I reckon a new PSU would be in place too. But I need something QUIET!!!!!!!!!! I hate that mixture of humming and buzzing. Apart from cpu, psu, mobo and ram is there anything else I should remember about? What kind of colling system maybe?

Thanks in advance everybody!!!!
Przemek

Well first of all, there are two types of i7 cpu's, some running on the 1366 socket and others on the 1156 socket. This restricts the choice of motherboard.

For a gaming rig that's future proof for a some years to come I would opt for the i7 on socket 1366. The mobo you mentioned supports those cpu's. These boards also support triple channel ram which 1156 one's don't.

The card you have is a good one to start with, but if it would lack performance you can always buy a second one and setup a crossfire system.

About the ultra quiet system. A gaming rig produces a lot of heat. To cool everything quietly you will need a big enough case, at least a large mid tower with many options to install extra fans.

Are you considering overclocking?

Hope this a good basic explanation. Please post further questions.

Not sure about overclocking, maybe I'll play with it a little.

From what I've read buying i7 is a better option in the long term.

You need to fill out the new build form instead of asking 15 random questons in 1 paragraph.

Any decent video card or case/cpu cooling is going to drown out any noise from a psu, so that's not relevent. There is no such thing as a quiet gaming pc unless your playing mah jong.



What??? Have you ever heard about silent parts? My PC is as noisy as an empty library. I use Noctua fans, a silent PSU from Antec and Sapphire Vapor-X 5870's, there is absolutely no noise coming from my gaming PC even on full load..

What chassis, cpu cooler are you using? Might be helpful for electrizer to choose the same components.

well there is noise, you just dont detect it :lol:  and heres what id do. if you want a quick an easy/cheap fix, get the i5. if you plan on upgrading in the future, get an am3 setup. am3 is cheaper, and slower, but unless you are doing some serious computing, you wont notice it. the good thing about am3 is the upgrade path to bulldozer and what not. although if you just plan on getting the parts, putting them together, using it for 4 years, then getting a new one, i5 is the better bet. and welcome to Tom's :)

Is there such thing as long term when it comes to technology? You know there isn't. When the that time comes, you will need to upgrade everything, because there will be a new CPU socket, a new memory type and new interfaces for hardware parts, storage.... Think about what you need NOW. If gaming is what you want, the i5 is a much better option.

It doenst matter what case. I replace everything with Noctua fans, all my cases sound the same. Because I use the same 3x120 fans on all of them...

o, and as far as quiet cases, id recommend the Cooler Master 690 II Advanced. It is an amazing case, but the beauty of it is that YOU make it quiet. At stock, its nothing special. But it has 10 spots for fans, so you can buy the quietest fans you can find, put them in there wherever you want, and you wont hear a thing. (if you do it right)

It's not because there is a new cpu that you will need it to play the games from that time. With core i7 you can play games from now and some years to come, especially if you oc it. When it comes to gaming, the vga is what you need to upgrade on a regular basis, not the cpu.

Exactly. that's why there is no pointing in recommending the i7 over the i5. the i5 is stellar in gaming and in a lot of benchmarks it even beats the i7.

Perhaps you are impressed with the i7 because you believe that 7 is better than 5. It's just numbers, in actual gaming performance, clock for clock the i5 is equal or better than i7.

But you do need to upgrade your CPU on a regulars basis, IF you would like to use a high-end video solution. CPU bottlecks GPU, that's why you need a good one. I use 2x5870s, without upgradinhg my CPU I'd have expensive paperweights inside my case...

Case really does matter. I have all my hardware in a full tower. Inside the temps are the same as ambient even under load.
I just build a pc with some hardware I had laying around into a much smaller coolermaster sileo case. This hardware gets very hot (though not as hot as mine) in there so I had to add a 2000rpm fan at the exhaust to keep inside temp within tolerance.

Lian-Li cases are much quieter than Cooler Master even without changing anything... Not to mention much higher quality.

Lian-Li lacks cooling as there are no standard fan mounts on top of the case.
They are the most beautiful cases out there though.

Full towers are for newbies and teenage gamers. Mature gamers user high-quality all-aluminum mid-towers from Lian-Li. Try one and you will get rid of that cheap Cooler Master POS in a minute...

no, not really. it doesnt beat it, you just wont see a large difference, since most games barely even use 4 cores, so the HT is irrelevant.

Why do you need top mounted fans? Do you like to have a jet engine in your case? Standard quite fans is all I need to keep everything very cool. If I'd need anythnig more extreme than that, I'd opt for water cooling. Lian-Li are 100% compatible with water cooling, but I don't need that. I don't do extreme overclock crap only for bragging rights, my Noctua fans are enough for 4Ghz without noise.

i7 is not just about the cpu. It's also about a 4.8gt/s connection with the chipset vs only 2.5gt/s for i5. It's about triple channel memory bandwith which really shows the power of DDR3. Dual channel on i5 doesn't. It's about at least 36 pcie lanes and even more with the nf200 chip so you can always install a true dual x16 gpu setup. With i5 only the better 1156 mobo's have dual x16 and these even cost more than a standard 1366 mobo like the asus p6t.

sigh, you all need to get informed! ok, dual channel and triple channel memory make a negligible, if any difference. pretty much same thing with the chipset. The difference between a x16 lane and a x8 lane is about 5%, so going from dual x16 to dual x8 is not gonna lose ya much. if you even go dual card at all.

LOL! :lol: 

Dude, triple channel is absolutely WORTHLESS for gaming, worthless! Show me just ONE benchmark demostrating that triple channel have ANY advantage over dual-channel, show me just one. :kaola: 

And you can use dual X16 GPU on any standard 1156 mobo, what you can't is true tri-SLI or dual CrossfrireX, but you can't with most 1366 mobos, either.

thats not ENTIRELY true. in concept, that is correct, and in practice, it CAN be correct, but due to blockage, airflow patterns, and cooling needs, going from the intake fan on the bottom to the rear exhaust fan USUALLY works best. However, in cases like the CM 692 advanced, you can have just about whatever air flow path you want, and with whatever fans you want.

everybody listen. heres how it works. if he wants an upgrade path, get am3 955. if he wants single gpu performance with no upgrade path, get i5, and if he wants dual gpus, 6 gigs of ram, or lives near a micro center, get the i7.

Dude, I paid 350 on my case. Money isn't the reason I don't have un ugly full tower in my room. And I have all the cooling and space I need. I have 2 SSDs and 3 HDDs, crossfired GPUs and full-sized coolers/fans inside my discrete mid-tower case and I still have spare space left... why would I need more? There is no reason to use a full tower unless it's a business server.

touchy touchy :non:  im just making a point you are speaking in absolute. have you take a survey saying ALL "mature gamers" (still get a laugh at that one :lol:  ) NEED to have 350$ lian li cases to be in your imaginary club of "mature gamers"? You see, mature PEOPLE buy the case that fits their budget. Im not gonna spend 350$ on a case, but thats just me. Next is their needs. Some people want big cases for lots of air flow and lots of room, so people like small cases for compactness and space issues. Their wants come next, some people hate LED bling, some people hate plain bland cases with nothing on them. I sit in the middle, i dislike the look of a lot of Lian Li cases that follow the corsair 700D case style. Its just too cut and dry for me, but i also hate crazy LED cases, maybe 1 LED fan, thats it. What you like is what you like, but do NOT make it sound like people are "immature" gamers just for not buying a mid-tower Lian Li case. that is absolutely absurd.

Man if you spend 350 bucks on a midtower chassis, I would have expected from a "mature" gamer to have at least GTX 480's in SLi. :kaola:

Geez, I can see that quite a discussion has developed while I was away :) 

Thanks for all the comments. I'll browse through eBay and internet generally in search for prices on i7 and i5. Problem is I don't have much info about what you guys are talking about here so I can't contribute.

I was thinking about sticking by the i5 due to lower price and my requirements. I don't do a lot of multitasking, don't do graphics, so I think that an i5 750 would be more than enough for me.

Cheers!

also, if you dont understand the difference between the i7 and i5, heres pretty much it:

i7:
  • faster QPI, although nothing can take advantage of it
  • On socket 1366, which will allow you to upgrade to cpus like the 970x, 980x, 990x and so on.
  • it has more pci lanes, and therefore can run GPU's on lanes with faster speed. it can do easily 2 lanes at x16, which is the fastest there is, where as 1156 can usually only do dual x8 (although the difference is only 5%)
  • triple channle memory, so you get 6 or 12 gigs instead of 4 or 8.
  • more expensive motherboards
  • it has hyper threading, which makes the OS read 2 threads for every 1 core, making it a virtual 8 "core". this isnt as useful as it seems, not much software uses it, and 1 thread doesnt equal 1 core, as they share resources.

    i5
  • slower QPI, doesnt matter
  • doesnt really have an upgrade path
  • it has less pci lanes, and therefore the max it can usually do is dual x8.
  • dual channel memory, so 4 or 8 gigs.
  • less expensive motherboards
  • On scoket 1156
  • doesnt have hyper threading, so its just an average quad core.

    for games, hyper threading is useless, and if you arent doing dual cards, i5 is the way to go.
    July 21, 2010 9:48:45 PM

    There you go :)  Nice and clear :)  I should be happy enough without a dual graphic card. Maybe I will overclock it instead. I'm not a benchmark freak, what matters is to be able to play comfortably. I'm not a DTP guy, don't to graphics, don't produce music and although I'm not on a very tight budget I don't want to pay for something I won't use to the fullest.

    BTW by the time I want to upgrade anything there will be new cpu's, new mobo's so I think that buying i7 just for the sake of its upgrade capabilities in not enough of a reason.

    ares, what was that thing with dual channel memory? 4 or 8 gigs? What's the deal with that?

    And Nils don't worry about that. That discussion was very informative to as I think I will need a new case and PSU as well so it's all good ! :) 

    Thank you very much for you invaluable help guys!!!

    yes, new cpu's will be out, however basically everything that is out now is all that will be on 1366, i think 990x is coming soon though. and dual channel, so you either have 2 or 4 RAM DIMMS, triple channel is 3 or 6 RAM DIMMS. most RAM modules are 2 gigs, so its more or less either 4 or 8 gigs, although you can have 2-16 gigs technically.
