Until something has changed recently, I don't recommend SLI at all. Not much performance gain vs single card. I'd go with one 980Ti.
Haha no worries, Durge, you're not going to upset me with that comment (SLI is a waste) I agree that it's sometimes a waste but other times it's freaking awesome . It depends on the game (and sometimes on the driver and user's system as-well). I've always gotten almost perfect benefit from SLI since it scales fantastically well in SCE, RF2, etc. with 3D Vision regardless of drivers (ateast from my experience), regardless of gfx settings, and regardless of # of monitors (1 or 3). The lego bits also had fantastic scaling in RF2 in 2D mode but that was from a couple RF2 builds back, I haven't tested the new build (although i think I read somewhere in this forum that either the new RF2 build or new Nvidia driver has once again broken RF2 2D SLI scaling). WhiteShadow, I'm not sure I understood your post correctly but the large framerate drops between different PCI-E speeds/lanes happens in RF2 regardless of wether you're running 1 GPU or in SLI. Check out DrR1pper's graph a few posts back (post #12 ); that's with only 1 GPU.
Thanks for all your help, after reading all replies i have decided on:- One gtx 980ti. i5 6600. ddr4. 8gig MSI Z170A Gaming Pro Intel Socket LGA1151 Skylake Motherboard. Has anyone got any comments on mini itx mb , i would like to get my pc to be more portable.
I would stick with ATX I not a fan of anything small for extreme gaming ( ie; GTX980Ti is extreme). 1/3 a GTX980Ti will hang off the Mini ITX board. You would be stuck with 2 x 4GB chips as they only have 2 memory slots ( or you would have to ditch them and get 2x 8GB ) Personally I think 8GB is plenty for single screen gaming unless you into number crunching encoding etc. Me myself I would go the H170 Gaming especially with a 6600 , performs just as well and none of the features of the Z are useful for you . ie: overclocking , 8x8x support , the extra sata and usb ports. H170 will run a 6600 and a GTX980-Ti just as well as Z170 My store ( aust dollars ) H170 is 209 Z170 is 289 That would pay for extra 8GB of ram or nice cooler or a small SSD ............ P.S. I do assume by 6600 you meant a 6600 not a 6600K
Well with a 6600@3.9Ghz the only things you pay for on a Z board are things you can't use or do not need. That is unless you need 8 hardrives and 12 USB ports etc. P.S. Audio chipset on H170 is the same as well, Realtek ALC1150. H170 uses 2133 DDR4 which is plenty fast enough
Agree H-chipset is also dam fast! Dont really know if theres a noticeable difference in any performance with Z-chip though, but I doubt. Especially when you want to be smaller, go with H on micro-ATX. From a manufacture-standpoint the better boards are the same as the ATX-brothers, but....smaller! So there should be no problem with a bigger gfx-card. H-chipset on micro-ATX here myself - all good.
Newegg...... Z170 Gaming Pro + 8GB G.Skill 2133-DDR4 = $200 US H170 Gaming 3 + 16GB G.Skill 2133-DDR4 = $200 US H170 Gaming 3 + 8GB G.Skill 2133-DDR4 + SanDisk SSD Plus 120GB = $200 US There is a performance difference but it is a few % in static / software tests etc. Not even measurable in Games. P.S. Same as 2133 vs 3000 ram games are no difference. Of course as Spin knows ......that all breaks down when money is no object and absolute performance is the goal.
Just a heads up surround will not work on the 170 chipset before this driver version 355.82 https://forums.geforce.com/default/...ound-not-working-on-new-z170-board-/?offset=4
If you like to simulate and come as close as you can to real life, less input lag better gaming experience, Nvidia 3D Vision, lightboost etc. than 60hz / 60 fps triple screens you go for 120Hz /120fps triple screens in rFactor 2. The only problem with your statement is that there is no single card which can make this possible and derfor i have question for you or some other ISI dev. Is rFactor2 never going to get any SLI support or working SLI profile?
