your cpu is one of the scam i7's from intel. its a 2 core, not 4 core, and performance is cut in half compared to the 4 core i7's around the same price. for comparison, your cpu is about the same speed as an i3 desktop cpu. you can try to sell the lenovo and get an i7 4 core with a gtx 970m or 980m.
This laptop I am on right now is a two year old design that plays 4K well but as Ronin has said your CPU is only half the CPU that is in this system AND you do not have a CUDA (nVidia) based GPU to help accelerate playback of MPE effects and features if it is required. Also your system has its maximum RAM already installed. I currently have 24 GB and this laptop has two storage devices which meets Adobe minimum requirements for Premiere, in my case they both are SSD's
Thank you for your quick answers!
I see the mistake I did
I am looking at various configurations with i7-4720HQ. Would nVidia GTX 960M be good enough ? I see performance wise it is well below 970M. I use extensively Warp Stabilizer and some other color adjustment effects
the gtx 965m would be lowest i'd go, staying away from the gtx 960m. if you are using just an effect or two with one or two color adjustments, the gtx 965m might work. the gtx 970m is a good step up to allow better 4k handling as well as more gpu effects and lumetri color, but it can add alot to the price tag.
Eric Bowen has reported here on this forum in the past that having more video memory on the GPU helps performance with 4K due to better frame buffering. At least 4GB of video memory on the GPU is recommended for 4K on a laptop.....although 2 does work OK...4 is better.
If you want to get a decent laptop, look at the Asus Republic Of Gamers G751JT-T7121H and make the following modifications:
1. Increase memory to 4 x 8GB.
2. Remove the 7200 RPM HDD and install a Samsung 850 Pro 1 or 2 TB SSD.
3. Optional: Add a Samsung Portable 1 TB USB3 T1 SSD
...yes...like Bill, I have an Asus G750JW from last year...self-upgraded the memory to 24GB and replaced the single suppied 1 TB spinning HDD with TWO Crucial internal SSDs. All runs fine, even with the older 765m NVidia GPU with 2GB of video memory. I was lucky....got it refurbished for $850 last summer and it arrived in like new condition.
However, if you can wait a little......new laptops are about to come out, ( some have already), that feature even BETTER performance than current models. The new 4 core Skylake desktop CPUs have tested BETTER in video encoding than the 6 core 3960X of "old". I'm not sure when mobile versions will appear. Some newer laptops are coming with a PCI SSD installed....providing data transfer speeds of over 1GB/sec. read AND write !
If buying new....I would make sure to have 32GB of system memory, ( either supplied originally or able to self-upgrade ), AND have the latest NVidia 9xx series GPU that has at least 4 GB video memory. Also, a minimum of TWO internal storage drive bays AND a high speed external port like my "mini displayport", which is the same as Thunderbolt 1.0...( although the new Samsung T1 external SSD runs at over 400MB/sec. read and write SOMEHOW on USB 3 !!....as reported here by Bill ).
...just wait until the new "Pascal" NVidia GPUs come out...and then later, the "Volta" GPUs !!!.....coupled with a Skylake E CPU, these machines will make my current machine look like an ABACUS !!!
Thank you all for the great advice! Should have asked first before bying
