if your video editing software support CUDA or Open CL GPU computing you dont need a very fast processor. . bettar to buy the video card with most cuda cores you can afford.. GPU:s are mutch faster than any cpu.. and way more price effective
Can anybody tell if the i7 4770k handle 4 gtx 970 sc please and answer my questions thank u
Can the i7 4770k handle 4 gtx 970sc just asking
Can the i7 4770k handle 4 gtx 970 sc and my motherboard is a z97-ws quad strength graphic power 4 way motherboard and my power supply 1200w 80p gold just asking
so many people seem to love the 4770k despite the 4790k performing better. i just switched from an amd fx 8150 to the i7 4790k. significant performance increases all around. glad i did it. was it perhaps more worth the money to get a 4770k though? i heard stories about how the 4770k output more heat and had a few other issues but nobody seems to be saying that here.
Your CPU is a Titan X? Lol....
lets hope! i7 4770 and 16g ddr 3 memory, thats all we need
I am so pleased cause i built my gaming pc in September 2013 with a core i7 4770 and i cant believe its still top of the line! I did upgrade my cpu to a titan x last year but thats it for the last 2 1/2 years
I will be getting i7 6700k to replace my i7 4770k, I don't think skylake refresh will be a lot faster than 6700k right now according to this tendency, i7 4770k = 4790k there is literally no difference between them.
I'll be rocking my i7 4770k for probably another year or two. Very good cpu.
here is a good example of a cpu. again you can change any of these parts according to what your budget needs. . The processor I included works with your editing software and is a much better candidate then the i7 4770k (2 more cores and 4 more threads.) and is cheaper by 100 dollars. And if you ever chose to everything is compatible with Edius 8 as well.
I have just realized that both of these processors WILL NOT work with Edius 7 because it is missing ssse3. you will need a processor that has the instruction set "supplementary SSE3". The i7 4770k will work but not 4790 or 4790k.
You can hand pick the best parts for your computers here: this is probably the best website for you to pick out pc parts because it checks if it is compatible with the selected parts. So I suggest a high end 4 core(4770k and the processor needs supplementary SSE3) or an 8 core processor if you have the budget for it. Which ever Processor you pick YOU NEED THE INSTRUCTION SET 'Supplementary SSE3'. Video rendering is strongly cpu based so that should be the focus point for your build. The graphics card dose not matter much, maybe a low end nvidia graphics card (gt530,540,620,630,640 with 2gbs video ram and more is better). The graphics card really depends on if you will be doing other things then rendering and Photoshop like playing games. Motherboards are hard to recommend because it heavily depends what you want from it. So this is where I heavily recommend using pcpartpicker because you can easily compare each motherboard and it's specs. Also pcpartpicker will tell you what brand the motherboards are and the best place to buy them. But I will say for the mother board stick with major brands such as msi gigabyte Asus so on. If you need help with or have questions go to the forum you can get more help there then I can give. Right ram almost forgot. You want a high amount of ram for video editing meaning 32+ just to be safe actually you are probably fine with 32gbs. Don't worry about the brand too much because there is not much difference between them. My personal opinion is go with corsair or gskill(gaming ram but it should not be a problem for for you and it is a REALLY good brand and has low price points.). The frequencies have to be the same as your motherboard allows and cpu but if you use pcpartpicker you won't have to worry about this. Also you want the the highest frequency that you can get even tho it is not much of an improvement it is still noticeable. Also you need a cpu cooler(i suggest an cooler master 212 evo) and you also need a psu or power supply unit and it needs to have enough watts for your system. You can pick out a good one on pcpartpicker and I recommend corsair or evga. So I guess that is it I hope you have fun with your builds and everything goes smoothly.
can u please recommend me the motherboard for the same and other configrations
Thanks for the sir and can u please recommend the other configuration of the computer ( motherboard, RAM, and graphics card) for edittine( Edius 6 or 7). Please recommend the company name also , so that we can purchase easily. Regards Varinder Sharma
Well probably the 4790k but i would suggest the 4790 over the 4790k if you are not going to overclock. Also get it from micro center if there is one near you because it is a lot cheaper but in store pickup only.
hello sir i want to purchase a pc for video editing( Edius 6 & 7) so can u please tell me that which is better i7 4770k or 4790k
For video editing you want more cores. So either the i7 5960x or the xeon 18+ core behemoths but dont be fooled, the xeon cpus were made for servers. so overall for editing you want more cores and the best one depends on your budget. Hell for 5000 dollars you can get an xeon Phi 7120A with 61 cores and i am pretty sure you can render a 4k video in seconds with that thing.
And for video editing ?
for gaming is best i5 4690k, the price is more low
