hey guys it's Black Friday maybe a lot of you are not reading the forum. :eek:

I am in Canada and I know we don't get good deals like the US, usually only Boxing day.

I know i5 3570k is good enough for any game.

But do you think this is worth it - i7 3820 $170 ? I know it requires a socket 2011 motherboard.

is it worth at that price or no?

I only do games with my computer. maybe some sony vegas rendering here and there but nothing serious. no graphic work or 3d or photoshops.

Well that price is really cheap.
Depends if the i5 is going for cheaper.

Buy whichever is cheapest.

Well there are some good combo i5 deals. I think I will pass on it. I guess I read to fast as I see it's Sandy Bridge.

This. Though not by much but then again the X79 motherboards are more expensive than the Z77 motherboards. In my opinion I only see X79 worthwhile if you were going to buy a 6-core CPU and make use of 6 cores, going tri-SLI or quad-SLI with high end cards or need more than 32 GB RAM. I currently own an i7 3820 but if I had to buy a new CPU and motherboard today, it would be an i7-3770k ($100 extra for the i7 is almost nothing to me) and a quality Z77 motherboard since I'm satisfied with a fast quad core CPU, 16 GB RAM, and one high-end GPU (don't have any plans SLI'ing, much less tri-SLI'ing).

well I passed on that and also on the i5 3570k asus p77 combo deal.

all these guys have the i5 3570k for $140 bucks, but instore only! how lame is that. nothing in driving distance for me. :(

Maybe I will see better deals in the morning. otherwise the Cyber Monday could be better...

Somewhat agree with this. The only reason you'd consider the 3820 is for the memory bandwidth.Although the 3820 is about equivalent to a i7 2600 (which is slightly faster than the i5 in most real world performance), the cost of the socket 2011 makes the i5 more attractive, especially for gaming. Plus upgrade opportunity for 3770k if you plan too w/o dishing out $500+ for 3930k. Essentially lga 2011 is build ground up for workstation users. Gamers are best suited by lga 1155.

However, I agree w/ hookies83 that ivy will give the edge to 3570k in gaming due to ipc improvements.

You did not just say that.

So a i7 is slower then a i5 in games ? Good info to know.

In this case yes...

3820 is Sandy after all and 3570k is Ivy... it's 4 cores are faster then the 8320s cores.

If i said games used more then 4 cores id be no better then an Amd fan boy lol.

The 3570K without a doubt. No need to waste extra money on a LGA2011 mobo, just to get similar or slower performance.

Essentially you only buy LGA2011 for 3 reasons. More than 32GB memory, more than 4 cores and/or more than 16 PCIe lanes for tri/quad SLI/CF.

primary advantage of going with the 3820 is that s2011 will have an upgrade path in the future, as you'll be able to drop in a 6 core CPU like the 3930K or even IvyBridge-E

the disadvantage is that motherboards are typically more expensive (albeit there aren't really any "cheap" s2011 boards)

if you went with the 3570K instead your only upgrade option would be going with a 3770K as s1155 is effectively end of life already given that Haswell is going to be on its own socket (1150)

granted, there's no guarantee that an upgrade of a s2011 rig would run less than a new Haswell or newer CPU + motherboard, or be better off as it will be hard to tell what will be more important, ie Haswell is going to introduce further IPC improvements (which could be rather substantial) but no more than 4 cores, while software has little choice but to continue to get more parallel.

for $170, id be all over that i7 3820, ya boards are a bit more expensive but you can run 4 memory channels and generally have more bells and whistles.

as far as upgrade path, that mostly a wash for me. by the time I'm considering an upgrade, usually at least 2 years down the line, if not more, the tech has changed so much it isn't really possible to just upgrade the cpu.

The upgarde path is also way slower. And you gonna sit with IB-E vs Haswell-DT. You even sit with the SB-E when Haswell-DT comes out.

If anything, much better to buy a mobo for half the price. And then buy a new Haswell+LGA1150 mobo than sticking to LGA2011 and older CPUs.

lol they said the same thing for 1366 and I ain't crying :)

I don't even know why you guys respond to these clueless post.

you would figure someone that has been on this site this long knows that 3820 is SB and 3570 is ivy and it has an IPC advantage and most games only care about 4 cores + clock speed + ipc therefore the i5 would be faster if gaming was your primary concern.

Even when I have him on ignore I can't avoid the uniformed thread crapping very sad.

Some games do perform better with more cores and with HT enabled CPUs. Battlefield 3 Multiplayer, upcoming Crysis 3, Max Payne 3 etc. More and more games are taking advantage of more cores and hyper-threading. My SB-E is faster in BF3 multiplayer than any Ivy chip out there, more so when you are talking about multi-gpu systems. That said, the 3820 is only a 4c/8t and the 3770 is going to be a better choice imo.

Cutting edge games are starting to take advantage of more cores these days. Here you can see a lower clocked SB-E 3930K @ 3.2 outperforming a SB 2600K @ 3.4 in several games.

Given the minimal difference between IB & SB performance and the SB-E outperforming SB at a lower clock speed, this landscape won't change using an Ivy chip. You also have to account for the thermal issues with Ivy generally leaving them hitting lower overclocks because of thermal limitations than you hit with Sandy; leaving them both on near even terms if you are an overclocker.



@ OP, I saw that deal at NCIX. Would of jumped on it myself at that price, it was one of the first things to sell out. The savings alone more than would recoup the extra $50-$100 an X79 motherboard goes for.
