GTX 1070 in Windows 7

It looks like I will be getting a bigger tax refund than I expected. I correbtly have a GTX 970 with 4GB Vram but I often have difficulty with needing more VRAM than I have; so I am considering using part or my refund to get a GTX 1070 with 8 GB VRAM. However, I am still using  Windows 7 64 bit. Has anbody used the GTX 1070 with Windows 7? Will the card and drivers work properly?

    I have a 1050 and a Titan X working in Win 7 Pro, 64-bit, using driver version 375.95 (which is also good for Iray, via DS).  There are earlier, and later, drivers that also work from what I have seen.

    It is also good to have enough RAM in your computer, as well. I think for 8 GB VRAM, you need at least 16 GB of RAM.

    I have 32 GB of RAM on Windows 7 64-bit and have no problems with the graphics card with 8 GB of VRAM.

    I have a 1080 running with Win 7 pro; no problems.

    Thanks everyone.

    @ Artini: I have 32GB in that computer so no problem there. However, your comment does raise a concern down the road. I had thought I might put my old GTX 970 with 4Gb VRAM in my old HP computer; but that computer only has 6Gb of system RAM. Will that be a problem?

    My cards have 8 GB of vram. Recently, I've noticed that larger scenes may take 6-7 gb of VRAM and 17 gb of RAM during the render. I assume it has something to do with compression when the textures are moved to the cards. I never expected to use more than 16 GB of RAM in a render, but am now glad I upgraded to 32, especially since RAM is considerably cheaper than VRAM.

    I have win7 x64 and a 1070 with 12gb system RAM. Renders fine. Last night I did a render with a scene, g3f with hair and clothes, and a LAMH fur wolf at 6,000 x 4,500 px size in about 3 hours.

    I recently upgraded from a 2 GB card to a GTX1060 6 GB card. I've noticed that saved scenes that fit in the old 2 GB card take more than 2 GB in the in the new card. I am left to assume that either the new card is less efficient somehow in managing memory OR it has some way of using compression dynamically based on available memory such that the more there is, the less compression is used. Don't know which it is.

    ...as my system is tri channel based the only physical memory upgrade I really can make is to 24 GB (from 12) so that should have me covered for compression purposes.  Theoretically I could go to 12 GB but 400$ for a 1070 is already a major budget stretch for me (on top of the memory and OS upgrade).

    You're missing some of the Direct X 12 improved parallelization speed that Windows 10 would bring but those cards should work.

    ...but DirectX is really only useful for games or video. As I don't bother with games nor stream video on my work system it is pretty much moot for me.

    I have 2 nvidia 1070 and use them both in windows 7 pro 64bit and they work very well with daz studio iray 4.9.

    ...sometimes hard to tell in discussion forums. Apologies.

    As I remember, GTX 970 does not really have 4GB of VRAM, but only 3.5 GB, but I do not know how Windows manage that.

    If you have sufficient power supply in your old HP computer, I think, you can give a try to put GTX 970 there, but check the power requirements for your GTX 970 first.

    HP is known to save on power supplies to desktops and the latest models has only 180 Watt limit there.

    Back when I bought the HP I considered expansion and put a 450 watt power supply in it. So, hopefully I should be OK in that regard.

    Actually, the 970 has 4GB, but the last 512 MB of the memory is not the same as the first 3.5 GB.  It's slower memory normally used for scratch space only, but it's fully addressable.  The problem is that if a game or render starts to dip into that last 512 MB of memory, things slow down dramatically.
