help me to choose, i3 vs i5 ivy bridge

[nickdc986]

Hy guys, my first post here.

I'm going to buy a new cpu, pc usage is for internet, download, office, 720p/1080p movies, cad applications and some rendering, i also want a pc with low power consumption.
So i have to choose between i3 3220 (110€) and i5 3450/3470 (around 175€). i5 is 65€ more, does it worth the price difference for my usage?

other components are:
asrock h77 pro4 mvp
corsair vengeance 2x4gb 1600mhz
ssd samsung 830 128gb
corsair cx430

thank you

If you're going to be doing rendering, I'd recommend going for the i5. The extra cores will really help.

Welcome to the forums!

i3 is more than adequate for office duties and movies but when you throw in CAD work and rendering you really need more muscle to keep things running smoothly. Go for the i5.

The rest of your listed components are solid choices. Do you plan to use a video card? Depending on exactly which CAD and rendering software you use, a discrete GPU may make a huge difference in performance.

165£ i5 3570K with HD4000 graphics too. Isnt it just to click buy?

 

[IntelEnthusiast]

I agree with the others for rendering the Intel® Core™ i5 is the best option as a matter of fact I most likely would go with the Intel Core i5-3570K

 

[AtenRa]

I will agree as well, if you can afford it the i5 is much better for Rendering.

First thanks everybody for suggests.
So when i talked about rendering i didn't meant professional rendering, but just playing around with google sketchup doing some amatorial stuff, cad software is autodesk autocad and i'm going to do only 2D drawing.

If this rig is meant for the basics, either will work just fine. Unless of course the basics would eventually lead to something more serious and a profit making career then it would be highly recommended to go with something that has the little extra even though you do not see the need in the near future.

I'm assuming that you're not using a GPU and relying on the IGP instead, getting the better Core i5 3570K with HD4000 is recommended.

Ok guys i'm going to buy an i5 ivy bridge, but which one of these: 3470, 3550, 3570?

 

[Yuriman]

Cheapest one. 100mhz frequency difference is something like 3%, which is usually within margin of error in most benchmarks.

Do you have any interest in overclocking? Do you already own the board you mentioned in the OP?

 

[nickdc986]

Thanks, i'm not interested in overclocking, the motherboard is already picked (h77 pro4 mvp).

 

[Yuriman]

Would you have any benefit from a better iGPU? The only two chips in your pricerange with the HD4000 are the i5 3570K and the i3 3225.

If not, go with the cheapest i5.

 

[nickdc986]

I'll buy a discrete vga in the future

I'd get the one with the best €/MHz

Hy guys, how much important are these technologies?

Intel® vPro
Intel® Virtualization Technology for Directed I/O (VT-d)
Intel® Trusted Execution

 

[Yuriman]

If you don't know you're going to use them, you probably won't ever use them.

Hy guys, how much important are these technologies?

Intel® vPro
Intel® Virtualization Technology for Directed I/O (VT-d)
Intel® Trusted Execution

vPro is hardwired ability of computer to be remotely controlled or supervised
VT-d allows running virtual machines with 64-bit OS
Trusted execution is some sort of security feature that protect running programs from any harm or data leaking

vpro functions are only included with specific CPUs and chipsets and are mostly found in business computers

VT-d is included in sandy bridge and ivy bridge i-line CPUs and trusted execution is also found on ivy bridge i-line CPUs

You wont use them at all so I consider they are not important for you

VT-D certainly dont allow you to use 64bit VMs. Thats still VT-X.

And about trusted execution:

And to the OP, all these are useless for you and doesnt matter.

Autocad says on its website that it is predominantly single threaded so you'll be better off with an i3 especially since you wanted to build a low power pc as well. Edit: http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=15224826&linkID=9240617

3450 180€
3470 185€
3550 194€
3570 203€

think im going with 3470
