I7-3770k with XFX Radeon HD 7950 BLACK

PS primary used for video editing, office and gaming.

might want a higher woltage power supply if your gonna overclock it, im building a similar system and i think im gonna get a 850w

In the details for that motherboard on NewEgg, it says "OC Genie II: Auto OC to boost performance in 1 sec" but in that price range I doubt you expect any results worthy of the effort. If you're going for the i7-3770K you'd do much better with a Z77 motherboard like the ASRock Extreme4 for OC'ing.

thank you.

do you think ASUS P8Z77-V LX, Socket-1155 is good enough

Yes, definitely.
I prefer ASUS motherboards and I have the LK (but I'm not OC'ing).

I just know that the ASRock Z77 Extreme series is popular among OC'ers and the Extreme4 is the same price as the LX.

i think i'll stick with the LK then 'cause my reseller don't have the Extreme4.

Last question before buying: Do you think that i7-3770k is worth the money instead of a cheaper one like i5-3570k?

Personally, I would go with the i5-3570k, depending on how much video editing you do. The i7 will bring hyperthreading support for multitasking so if your priority is video editing go with i7. If its more for gaming, the i5 would do fine. The PSU is fine (actually you could get by with 550W, to be honest). The CPU power rating is only at 77W. I have two GPUs, 25% OC on a 95W Phenom X4, four HDDs, multiple fans, etc. and I only have 750W. As sharkbyte said, you definitely need a board with a Z77 chipset.

i7-3770k will perform better in video editing, but you'll see no improvement in gaming.

Also there's no need to consider a stronger PSU, the one you've chosen is more than you'll need to run those components. If you were considering Crossfire for later you could look at a 750.

That's true, it depends on how fast you need your work done. For Video Encoding the difference might be minor between i7 3770k and i5 3570K, for some professionals it matters every second and definitely you need much RAM, 16 GB is recommended for video editing system.



The advice by USERTnite is extremely wrong, a 650w is very sufficient.

Also, you may consider to add a cpu cooler, it's much better than stock one.

The WD Caviar Blue or Black are faster and better than Green.

I have heard that the i5-3570k will bottleneck the 7950k black (900mhz). also maybe the hyperthreading technology will great in future games?

For video editing, looking at those charts you're talking about an advantage of only seconds between the 3570K and 3770K, but software companies are definitely working to make games that take advantage of hyperthreading and other high-end features so the 3770K will serve you better in the long run for being more future proof.

Your PSU is sufficient as long as you're running only one GPU.

I agree that you should get a CPU cooler, especially for the "K" series. Stock coolers are sufficient for very basic use that does not include OC'ing. The Cooler Master Hyper 212 is popular and inexpensive.

Yes the Green series hard drives are slower because they're designed to be more eco-friendly, go for Caviar Blue or Black.

Western Digital® RE4 Enterprise 1TB? there is also 5 years warranty instead of 2 on the green

Whoever told you that is insane.
The i5 3570k is far from bottlenecking anything, there is no bottleneck from a 3570k/7950 set up.

I built a business workstation for my sister and used the RE4 Enterprise and it's good but just FYI it can be a bit noisy at times.

with a seagate barracuda you can get 2tb for the same price.
