Need a GPU for Lightroom 5.7 photo editing on a 27 incher monitor and 4 year old rig

[philmar]

Impulsively I went online all of last night and in to the early morning and in a sleepy mindset I pulled the trigger on a BenQ SW2700PT.

When I awoke this morning I realized that I'd neglected to consider whether my PC can handle it. My expertise in pixels, not bits and bytes.

I don't have a graphics card - I use the onboard Intel® Z77 chipset graphics: Intel HD 4000 on my Ivy Bridge i7 3770K
My mobo is the ASUS P8Z77-V PREMIUM (external link).

From what I've subsequently read the new monitor's increased resolution and resultant complex calculations will tax my CPU. I'm wondering (hoping) that a dedicated GPU will help.

I do NOT game or edit video. I do only light netflix viewing but the biggest demands on my system are RAW photo editing. Moving pixels around and displaying it on a high res monitor involves a lot of CPU calculations.
Will a GPU help my pc performance?
My understanding is that Lightroom 5.7 does not make use of GPU acceleration. A new LR 6.0 version does and this may force an upgrade for me.
I was hoping for a complete new rebuild in 2 or 3 years. I hope it isn't required as a result of the new monitor purchase.
Any recommendations on the best value (bang for buck) GPU that could help me (and ideally be used in my next build)?
I run W10 64 bit, 32 GB RAM, 1 SSD and 2 spin HDs and Antec 620 W PSU.
Sincerest thanks for any helpful suggestions!

I found a Lightroom faq which indicates Opengl 4.3 support is required, I found a faq which indicates Intel HD 4000 graphics support Opengl 4.0. So you'd need a videocard for hardware acceleration in any case, regardless of your monitor resolution. To be honest, with the 32gb ram you have and that good CPU, I'd be surprised if you were having trouble working in Lightroom with no hardware acceleration, even at 1440p.

Thanks! I was happy to hear my i7 3770K is a good CPU even after all these year!
I think the GPU acceleration only is required in LR 6, not LR 5.7.

I realize the following site is a commercial site devoted to selling you hardware but their advice is interesting.

" Video Card (GPU)
In Lightroom CC 2015 and Lightroom 6, the software is able to utilize the power of your GPU to improve performance when editing images in the Develop module. At the moment, the performance gains are fairly modest, although Adobe has been investing heavily in GPU acceleration. While a high-end GPU is not required to get the benefits of GPU acceleration in Lightroom, it may be a good idea to get a slightly faster GPU than you think you need to help future proof your system.

Lightroom is also very light on VRAM requirements, so even a card with just 2GB of VRAM should be more than enough. However, if you work with large images in Photoshop or use a 4K monitor it is a good idea to use a card that has at least 4GB of VRAM if possible. Workstation video cards are not required for Lightroom, although if you will be using a 30-bit monitor you will need a NVIDIA Quadro video card as GeForce cards currently do not support 30-bit display output.

Although it is likely that Adobe will increase GPU acceleration support in Lightroom in the future, the current demand on the video card is actually relatively light. We recommend either a GeForce GTX 1060 GeForce GTX 1070. "

Is my BenQ SW2700PT a 14 bit monitor?

My mobo is the ASUS P8Z77-V PREMIUM which has one DisplayPort and one Thunderbolt port. My BenQ has a DP port.
Curiously the monitor does NOT ship with a DP to DP port cable. However, it DOES ship with a Mini DP to DP port cable. Someone told me I could run the monitor with the MiniDP end of the supplied cable plugged in to the mobo Thunderbolt port and the DP end plugged in to the monitor. Is Mini DP compatible with Thunderbolt? Even if the supplied cable does work, would my monitor run better with a DP to DP cable?

I find information from sites like that helpful not because you take it as gospel, but because it gives a starting point of things to consider. Of course you then look deeper in to the aspects that concern you.

I would just run a DP to DP cable. I believe that is a 14 bit display. Also, if you want this best results in Lightroom you'll want to calibrate the monitor or have it calibrated. I'm not sure if you've looked into that yet.

Received the monitor today and setting up was a breeze. Base, arm and screen easy to assemble.

Had absolutely NO problems running it on my 4 year old processor's HD4000 graphics - even have the NEC 20WMGX2 as a 2nd monitor with both running at their native resolutions.

The BenQ is at 2560x1440 - w10 drivers were installed but not as easily as the manual said it would be.

Good news: It is connected using the supplied mini DP to DP wire: the Mini DP plug in my Intel mobo's Thunderbird port and the DP plug in to the monitor. Never thought that I'd ever use that port but am so glad I didn't have to go out and waste an hour buying another cable. Still don't know why they included it and not a DP to DP cable.

I am happy to say that I see almost NO performance degradation with LR 5.7.

Small difference: when in Library mode and scrolling in Grid view is a bit choppy.

Small difference: Bit more time required to cycle between regular and zoom when in Loupe view.

Performance differences are negligible - to the point I regret the considerable time I wasted researching it. Guess my i7 3770K and mobo were good choices 3 years ago...and happy I won't need a GPU!!

Though it is early days thus far...I'll report any issues.

Did a system upgrade. Monitor is playing very well with LR now. At time of first use, it was slowing down when I was using crop tool - this forces LR to change zoom to fit in to screen. As a result, I added a second SSD as the LR lrdata previews file (> 100 GBs) had almost filled my SSD C boot drive. Also I swapped out a spin hard drive that was dying with a new one. The problems disappeared completely.

I'm not a techie, but I suspect it had to do with the windows page file being on the 'soon to be toast' data dick drive as well as the fact performance was degraded by my boot drive being near capacity. I've moved the LR catalogue and all the lrdata/lrcat files on to a new secondary SSD drive.

One or both of the actions above has resulted in a performance boost. My i7 3770K and intel onboard 4000 graphics are now running LR on the BenQ with NO appreciable perceptible difference when compared to the smaller 20 inch monitor I used previously - and have hooked up as a second monitor. Also I calibrated the BenQ with the BenQ software which adds the profile to the monitor's LUT (just reporting what I read - can't say I understand what that means). Someone suggested that this could also take some of the burden off of the CPU.

The only difference I see now is when I scroll quickly between files in the Library mode. They take longer to come in to sharp focus that they did previously.

I did all these changes at the same time so i can't say with any certainty which of the 3 things contributed most to my performance boost.

I'm wondering if even a cheap vid card would help a bit - anything $100 or less.
Also do I lose something by using the mini-display cord plugged in to the thunderbolt port? Could a a cheap GPU take some of the load off of the CPU?
Would anything be gained if I had a cheap GPU with a display-port port that I could use a display-port to display-port cord with?

Can you tell me, how many SSDs you are now running?

1 for The System an LR ?

1 for the source files?

1 for the scratch files?

And when your are finished, everything goes to a hdd?
