That depends 100% on the application. The main difference between the 2 processors is the HyperThreading feature of the i7. This allows multi-threaded applications to more efficiently use the CPUs resources. The problem is that most programs don't make much use of multi-threading beyond 2, perhaps 3, threads, which any regular quad-core CPU can handle.

A game like SC2 will get no benefit from HyperThreading. Some other games might, but even then it's rarely worth the difference in money. Streaming, on the other hand, is something that can take advantage of an i7. If you're heavily into streaming, the i7 might be worth it. Some other programs, like video editing, could benefit from an i7, but again it's highly dependent on the program(s) you use.

While in the best-case scenario, the i7 can offer up to 30-40% more performance over the i5, in general, the probability is rather high that you're better off investing the difference in price between the i5 and i7 into something else. For advice more suited to your personal needs, we need more info.

To add to Rannasha's post:

In terms of x264 (the video encoder that OBS, Xsplit use) you see about ~20% gains from Hyperthreading, but the tl;dr is that in a regular streaming setup, i don't think that you can actually get more FPS in sc2 from having it (i'l test this to verify)

It opens the option of encoding at a higher framerate if you have for example a 1920x1080 stream you could maybe stream at a higher FPS without hitting cpu limits on i7, but it mostly comes into play at extreme streaming settings, like i think >48fps, 1920x1080, and it's not really ever appropriate to do that IMO.

I'd get HT for streaming games at a high resolution and FPS that heavily load the CPU, for example Crysis 3, but not for stuff like starcraft 2 and planetside that will look at an 8 threaded CPU and use 1.5 (or in the case of planetside 2, less) threads. They are CPU bound while leaving most of the CPU idle and available for encoding a stream.

I can confirm though that without heavily loading the CPU (like say 1920x1080, 60fps stream output) ht on vs off is literally identical in fps, i got two benchmarks in sc2 with minimum and maximum FPS the same and average within like 0.1%

Pricematch NCIX's price of the core i5 4670k at Memory Express to get it for $230. Should have bought three weeks ago when the i5 4670k was $195.

Samsung 840 120gb is on sale at Newegg and NCIX for $90, pricematch at Memory Express for $87.

Pricematch the Gigabyte Z87X-D3H from NCIX ($135) at Memory Express to get it for $128.

Pricematch Noctua NH-U14S from Newegg ($68) with Memory Express to get it for $63.

Not going to be any sales on a GTX 760, you can get one at Memory Express for like $240-$260 depending on which model you want.

It's the Intel Management Engine device. If you install the drivers/software for it from your motherboard's support website, it should go away, but you can also ignore the error. I think it literally has no use whatsoever on a PC at home and will install and run a bunch of services, so you might be better off not installing the software.

It might also stop being logged as an error if you right-click and disable the unknown device with a yellow exclamation mark icon in the device manager. That one should be the Management Engine device.

EDIT: You might want to try a program called "blue screen view" to see if it finds past bsod's and shows the codes and perhaps some info about if a driver was involved.

Z87X-D3H is $134.99 at NCIX, not $124.99. The after mail in rebate price is not the price you pay at checkout.

Not sure how fast you want it but standard shipping is generally five days if you live in Ontario or BC so you'll end up getting it Thursday, Friday or Monday at the latest.

The video card uses ~150w max. Your full load power consumption probably wouldn't hit 300w unless you overclocked CPU high and GPU considerably

I'd grab some ~2400 ram if you are overclocking CPU, it helps a lot in some cases. Not many, but 4.4ghz cpu with 2400 ram would outperform 4.6-4.7ghz cpu with 1600 in sc2

People get less all the time, for an intel quad and single GPU system the corsair cx430 and rosewill capstone 450 are pretty popular buys

~2400 ram shouldnt cost much, there's been several deals recently for 8gb of it for $70 (or even $60), there's a ton on this page for example: http://www.newegg.ca/Product/ProductList.aspx?Submit=Property&N=100007611&IsNodeId=1&PropertyCodeValue=524:55450,524:288992,524:301742,524:301744&bop=And&cm_sp=Memory17-_-VisNav-_-ExtremeGame,Memory17-_-VisNav-_-ExtremeGame&Order=PRICE&PageSize=20

The ram you linked though is 2133cas11 @1.5v, so you can probably get a bit more out of it by running at 1.65v like most of the other RAM kits would have you do anyway
