Real time video editing, is possible?

Question

Hi to all, first of all thanks for reading this post.
I would want to know if it`s possible to apply some effects (mostly twixtor, some warp stabilizer, color correction) and see the result (maybe at lower resolution, 1/2,1/4 resolution) without rendering, but fluid (to verify the image goes accordingly with the audio, to see the speed change is adecuate with twixtor, etc...)
I have a laptop  that is supposed to be powerful: i7-4800mq, 16 GB of RAM, GTX765M, and (maybe it´s the reason I don´t see the expected result) a 7200rpm hard disk (SATA 3GB/s, with 64 GB SSD catching mSATA)
I use video primarily recorded from a gopro 3 black, and use premiere pro cs6, after effects. 1080, 60 fps.
I want to change my computer because I have to do a lot of editing of short videos, lot of twixtor, and can´t wait to renderize every time I change something and the bar goes from green/yellow to red.
I would want to know:
-if this is normal, with my computer
-If you where to going to buy a computer, instead of asking which component you should buy (of course you can), what do you think about these two:
option 1:
i7-4790K 4.0Ghz
MSI GeForce GTX 980 Twin Frozr V OC 4GB GDDR5
Motherboard: MSI Z97 Gaming 9 ACK
Hard disk:
Seagate Barracuda 7200.14 3TB SATA3 64MB
Samsung 840 Evo SSD Series 500GB SATA3 (250GB x2 in raid 0)
Kingston HyperX Savage DDR3 2400 PC3-19200 16GB 2x8GB CL11
price: around 2100 euro
option 2:
i7 4790K
2x GTX760 2GB GDDR5
Motherboard: GA-Z97X-SLI
Hard disk:
- 2x HDD 1TB 7200rpm Seagate ST1000DM003
- 2x SSD 120GB Kingston V300
16GB DDR3 1600MHz (2x8GB) HyperX Fury Blue Series HX316C10FK2/16
price: around 1600 euro
I know I can use proxyes but I think proxyes with less resolution give problems with warp stabilizer and with less fps give problems with twixtor.
Do you think I will be capable to do real time video editing with these computers? Thank you very much!

Answer 1

....read about your laptop....the good, the bad, and the ugly.
...ugly first : you are right ...16 GB is the max memory that can go in your machine.....I believe that will hamper performance  with some heavy timelines,but, not sure. My laptop could take 32GB, but, 2 of the 4 slots are inaccessible, so I wound up with 24GB. I have seen the memory usage swing up to 20GB during certain tasks,but, not most of the time.
...good : your CPU and GPU are FINE.....even BETTER when you over clock the GPU "memory clock" with the free "MSI Afterburner " utility...I go "plus 903 Mhz"
...the BAD : its NOT hopeless, however. Your CURRENT storage configuration is a DISASTER !!!....a definite bottleneck which will cause huge problems with Premiere Pro.  The GOOD news is that it can be EASILY fixed. RIGHT NOW, you have a single 7200 rpm HDD with EVERYTHING on it and a SMALL mSATA SSD acting as a "Cache" for the hard drive, to help speed it up. That is effectively having just ONE drive, and that is below spec for PPro, which needs TWO separate drives as a minimum....( with the now way higher speeds of SSDs, some argue 2 drives are NOT really needed, if ONE is fast enough....but, thats not altogether true).
Easy solution : replace the current mSATA 64 GB SSD with a crucial M550 mSATA SSD, ( ONLY Samsung Pros or Crucial M550s are recommended for use in machines doing video editing...there are reasons for this.....the 550s are WAY cheaper and only SLIGHTLY behind in performance.....hardly noticeable. ( $150 for 256GB, $250 for 512GB at B and H )
If you have the Windows disk, you can do a fresh Windows install on the new, fast SSD. If no disk, just CLONE your existing HDD "image" onto the new SSD...( provided it will FIT !! ) . Now the new mSATA will be your FAST boot drive !!!.....reading and writing at over 500MB/sec instead of the SLOW HDD running at 120MB down to 60 MB/sec with all the LATENCY and FILL degradation !! On this mSATA, you would have OS,programs, and Windows page file ONLY....( although if you get the 512GB SSD, you can experiment using the extra space for all cache files, previews, and exports).
NEXT.....take out the 7200rpm drive...replace it with another 2.5 inch Crucial M550 SSD !!!.....go all the way up to 1TB if you want !!, ( $450), or, at least 512GB. Place ALL other files here
Using these two new SSDs will MASSIVELY improve your performance with PPro......but WAIT !!!.......THERE'S MORE !!!
You have OTHER storage options as well. If you really want to go nuts, you can REMOVE the DVD drive, and use THAT SATA port for a THIRD SSD drive. I have read where someone used an M.2 drive as the boot drive,then created a RAID 0 with the now TWO 2.5" SSDs in the machine....( your BIOS allows it,I think) That would give you a huge "D" drive volume running at OVER 1GB/sec. for serving up all your media. project files and all else. There are plenty of "how to" videos for YOUR machine on youtube, as well as forums like "notebook review" where owner's describe upgrades they've done.
Finally, you have a "mini-display port " AND a HDMI 1.4 socket. On MY laptop , I have the EXACT same mini-display port connector, but, it is called "Thunderbolt". I have read that with THIS connector, "Thunderbolt" and "mini-display port" are INTERCHANGEABLE !!! What it REALLY is , is a high speed data connection that is FULL-DUPLEX, ( UNLIKE SATA which cannot write while reading and vice-versa). Your version is probably 1.1...like mine. The newer 1.2 displayport connection can handle 4K .  The 1.1 speed is actually about 8Gbits/sec, ( or, 1 GB per second BOTH WAYS). This means it MAY be possible to connect a high speed thunderbolt storage device to that port....I am NOT sure....but I think you CAN because the HDMI 1.4 port handles my 2560x1440p IPS monitor at full resolution...yours should ,too. However, the mini-display port  may be configured for video screens only without a "Thunderbolt" driver....I am not sure. Thunderbolt storage is expensive and not well developed yet.
You may ALSO us the USB 3 external port to get a decent speed for external storage. What I do is use a cheap $30 USB3 dock, that has both 2.5" and 3.5" slots in it. THEN, you can plug SSDs,or,HDDs in to it....changing them like "cartridges"....you will get up to 220MB/sec using SSDs in that, and normal 100-120MB/sec with a 7200rpm HDD.Its great for putting previews, cache files on....those are all easily recreated by premiere if ever lost or erased.
So, SPEED up your storage configuration and you should be greatly improved. I found an AWESOME 27" IPS monitor on sale for only $299 that has the WQHD 2560x1440p resolution that would be KILLER hooked up to your laptop, which would EASILY drive it. The pixel density is AMAZING......1440p videos look like 4k on it !!...that's ANOTHER option you have.
