    That's great feedback and good to hear that Intel iGPU is working well with HWA. The latest iGPU I have to work with is on the i7-4790K (iGPU HD 4600), and I haven't gotten around to testing it. I'm planning on ordering a new i7-7700 (iGPU HD 630) system this week, so would be interesting to test both them out and compare. Maybe it depends on the MB, but what's the port situation for you if you want two displays? I know you said you don't need fancy graphics, but just for comparison, what if you do turn on shadows + ambient shadows in a consistent shaded view, what's the performance like then with the iGPU? "Realistic" view + shadows?

    The GTX 1050/1050Ti is a no-brainer for a $100 - $150 GPU that will be perfectly adequate (even with all the eye-candy turned on) for the majority of users on SD displays. It's roughly equivalent to the M2000 (which was a giant step up from the previous Quadro 2000 series).

    We're moving to dual UHD (4K) displays, and that's where a beefier GPU is definitely needed (in my experience so far). We're still trying to find the sweet spot if that's the GTX 1050 or GTX 1060 or GTX 1070. This stuff is also very relative and subjective... I've seen performance that some people think is perfectly fine that personally would drive me bonkers.

    We recently purchased new W10 machines. We were able to get i7-7700k, M.2 storage, and 32GB RAM. For the kind of work with do (security and telecom), renderings and pretty 3D views are not very common. However, we do work on large models, with combined linked model file sizes easily over 2GB.

    Compared to our previous setup, Xeon E5-2620 v3, traditional HDD, same RAM, the difference is night and day. Using the RFO benchmark, the new setup is literally twice as fast.

    But all of that is a little off topic. We are still considering our options for GPU. I have been using the integrated graphics for several days with no noticeable difference in our day to day work. I have not had any issues with HWA on. So far we have only compared to a Quadro M2000 because we had one available. Using the RFO benchmark tool revealed a slight edge to the Quadro (81 vs 96, I can post results). I find that pretty remarkable.

    Lastly, I also tested a little with HWA on and off with the integrated graphics. This was in Revit 2017. If anything I would say performance was worse with HWA off. This was most noticeable rotating and working in 3D views. Again, keep in mind the type of work we primarily do.

    At this point I am considering just getting GTX 1050 Ti cards. They are inexpensive and don't require additional power like 1060 on up. This means they should work in our OEM Dell machine configuration/power supplies. I'd be interested to get opinions on that.

    Thanks.

    Wow thats good to hear about your experience so far. If I were to comment on the 1050/1050ti is that it is a pretty good card. The 1050ti is basically the same performance of the GTX770 or close to the gtx960 (could trade blows with the 960). I would recommend the 1050ti though for the 4GB of ram which I think is worth the small increase in price.

    I have not heard of this issue on Nvidia cards but if you experience issues with system stability on a pci-e only powered video card, it may be the motherboard not supplying enough power to the pci-e slot or the GPU is pulling more than the 75watt pcie standard (what happened to AMD at the launch of their new cards last year).

    Again I only read that issue on AMD cards but keep that in mind.

    Thanks to both of you for more info. Special thanks to you iru69 as your posts on CPU and GPU have really helped me sort through details for Revit specific hardware decisions.

    In regards to dual monitors, the iGPU I have right now (also the HD 360 I believe) came with dual DP and that's what we normally use: dual 23" at 1440p.

    I'll try to do some testing next week in regards to your questions on realistic view detail with shadows.

    Oh new computers It will depend on the motherboard, some of the ones I have seen will have a display port and two HDMI (not sure but probably 1.4 but maybe 2.0). The nice thing about selecting your motherboard is that you can pick the layout. The igpu can do 3 displays too. I have used the 7700k igpu to watch 4k youtube on my monitor but no professional applications, I have a 1080 in my system for the fun stuff.

    For 4k panels I would recommend the gtx1060 6GB card ideally then the 1050ti 4gb. I would say 1060 3gb except it is a cut down version of the 1060 and not just a RAM loss, I think for professional applications I would rather have the extra RAM in this case to be flexible. If you ran out of RAM on a gpu things would suffer more than just having less cores on a gpu.

    What size 4k panel are you going with? We decided to stay with Dell 27" "color accurate" 1440p monitors since even on a 29" 4k panel we needed the scaling at 150% to be functional for most people. Ultra wide came up but we felt that the dual 1440p was still more useful.

    Also while most of the office is on Titan X cards (for lumion), the oldest card about to get retired is a GTX680 (the 1050ti should beat it) and no complaints with dual 1440p in revit. So while 4k is still a lot more pixels, I find the CPU seems to still be the biggest issue to keep architects happy so long as a decent GPU is used. An architect was using a dual e5 2687w v4 system we got for 3ds max renders (3ghz min.) with a Titan X pascal and when we gave him his new 7700k gtx1080ti system last week he was just SOOOoooo happy with it. Now the render machine can be used for just that haha (3ds max and lumion).

    I would also like to just add that the GPU from the previous computer (CPU and storage noted above) had a Quadro K4200. The previous machines were not selected by someone particularly interested in heavy daily Revit use. Probably an adequate card in it's own right but still overkill, overpriced, and not particularly suited for our needs.

    Regardless, for those in the know, the significant performance improvements from changing to the i7-7700k and M.2 are probably not surprising. For those researching hardware for Revit use for the first time, I can't agree enough: get the fastest CPU and storage drive you can afford. Then select the GPU on your specific needs. If cost is an issue, *almost* any recent GPU will do.

    Dell 27" P2715Q. Great display at a really reasonable price. They also have a really well done matte screen. They have excellent color accuracy for this level of display... may not be considered good enough if you're doing fashion magazine spreads, but plenty good enough for AEC.

    Scaling is of course necessary - anywhere from 150% to 200% depending on comfort level. I've been using 150% for many years even on my 30" 2.5K displays with just very minor quirks, and these days, 200% is completely usable aside from the odd-ball app or old software.

    The model Dell we went with was the UP2716D. Scaling is not too bad with windows 10 like before and I do live with it on my system as well. Thanks for the information.
