GTX 1080 SLI is way overkill for lower resolutions such as 1080p. For a 60 Hz monitor, even a single card is sufficient as its framerates stay close to or exceed 60 FPS in most of titles. NVIDIA's decision to facilitate higher resolutions such as 5K and using modern DisplayPort 1.4 connectors, and the new SLI HB multi-GPU interconnect with over three times the bandwidth of a classic 2-way SLI bridge, show that the company believes that GTX 1080 SLI can provide playable frame-rates at those resolutions.Ī GeForce GTX 1080 SLI setup should prove useful if you have a 120 Hz WQHD (2560 x 1440) monitor. is also the highest monitor resolution we had at hand. The GTX 1080 duo makes short work of any current game at 4K Ultra HD resolution, with framerates exceeding 60 FPS in most games that scale. The 560 ti is a decent card, but you will not be able to max out BF3, nor will SLI help in any way.Value and ConclusionAt close to $1,400 (as low as $1,200 if you consider the $599 baseline price and $1,300 if you consider the $650 mean price of custom-design cards), GeForce GTX 1080 SLI is the fastest dual-GPU solution, although any claims of being the fastest graphics solution money can buy could be disputed by the fact that the GeForce GTX Titan X and the Radeon R9 Fury X support 4-way multi-GPU. You can't turn the 2 AA settings on without the VRAM filling and causes fps drops, so a second card will not help. Everything else is maxed out, but not the 2 aa settings (MSAA and post aa deferred or whatever it was called).ĭEFINITELY DON'T GO SLI with a 1 GB card for BF3. Moral of the story, at 1680x1050 without even maxing the settings, the VRAM is FULL. This may be playable to some, but not for me.
If I turn the the HBAO type of aliasing on, there are occasional drops to 30 FPS (minimum) but mostly above but quite regularly dropping below 60 (30's, 40's).
This tells me that HD (1920x1080) will certainly be VRAM limited at this setting. I have to disable the HBAO, and completely turn off MSAA to maintain 60 fps (minimum) (turned on vsync to verify, it never drops below 60).Įven then, it's already using 1 GB of memory. Playing battlefield 3 with 1680x1050 resolution, It's overclocked to 1000MHz core, (reference is 822MHz) so it's considerably faster then the reference and is already at reference 570 speeds.
