wolle Posted July 4, 2015 Share Posted July 4, 2015 I run a computer with a single NVidia GTX 770. Am I correct that buying a second, identical video card will give me the best bang for my buck once DCSW2.0 has been released? In any case, I need your advise, since I am hardware-illiterate: is it as simple as buying a second identical card and sticking it in the appropriate slot on my computer, or is it more complicated than that? I have heard the terms SLI and Crossfire used for running two cards in parallel. Are those software solutions, or do I need to buy a special cable to connect the two cards, or what? Your advise would be greatly appreciated, and keep it simple, please, I am not familiar with most computer-speak...

cichlidfan Posted July 4, 2015 Share Posted July 4, 2015 (edited) Crossfire is the AMD version and SLI is Nvidia's. Nvidia cards will come with part needed to connect the two cards. Yes, you want the identical card. You do need to have the appropriate slot available on the mobo, of course.

Demon_ Posted July 5, 2015 Share Posted July 5, 2015 You only need another Gtx770, whatever the brand. You need the power supply: http://www.realhardtechx.com/index_archivos/Page362.htm As long as you don't know the distance between the two cards, purchase the flexible one (SLI bridge): Attache ta tuque avec d'la broche.

Demon_ Posted July 5, 2015 Share Posted July 5, 2015 I think the term "identical" is used for "identical gpu". Attache ta tuque avec d'la broche. Link to comment Share on other sites More sharing options...
cichlidfan Posted July 5, 2015 Share Posted July 5, 2015 Yes, identical GPU but I would also try to match memory amount so one card doesn't have wasted memory.

ctguy1955 Posted July 5, 2015 Share Posted July 5, 2015 Two GPU's video are added together now in DX12 I really like the fact that the new Win 10 has DX12 and my two 4 gig gpu's will now actually be running 8 gigs of video ram now !!! :pilotfly: Link to comment Share on other sites More sharing options...
Demon_ Posted July 5, 2015 Share Posted July 5, 2015 Very good, but i think EDGE (in 2016-?) will use DX11: http://forums.eagle.ru/showthread.php?t=135473 Sorry for the bad news. Attache ta tuque avec d'la broche. Link to comment Share on other sites More sharing options...
wolle Posted July 5, 2015 Author Share Posted July 5, 2015 Thanks for the advice, guys. I have an 850 W power supply, and this is just what I need (according to Demon's link) for 2x GTX770 SLI (assuming that recommendation includes also enough power for the remaining hardware). So, my question now, in people's experience is 850W enough to run 2x GTX770 SLI plus the rest of the computer?

Coxy_99 Posted July 5, 2015 Share Posted July 5, 2015 I also have 2 gtx 980's in sli running off an 850 watt psu, All i need now is a better monitor im limited to 60 fps so a new monitor would be ideal in the next step, Is it true you can get better SLI connectors between cards ? or doesnt it matter.

Your advise would be greatly appreciated, and keep it simple, please, I am not familiar with most computer-speak... SLI is actually really useful and quite fun. Just gotta makes sure you understand not all games support it and sometimes games are just poorly optimized for it, if you're getting it for DCS world 2.0, you'll be set, they are heavily invested into making it SLI/CFX capable. I bought 2 570's back in the day and was super happy about the buy, just switching from SLI on and off i saw a huge difference (atm using a 980 TI SC). The only thing you need for SLI is to make sure you're on the same core clock of both cards. A superclocked factory card won't work with a non superclocked card for SLI. Thanks for the advice, guys. I have an 850 W power supply, and this is just what I need (according to Demon's link) for 2x GTX770 SLI (assuming that recommendation includes also enough power for the remaining hardware).

Brewnix Posted July 21, 2015 Share Posted July 21, 2015 Wolle did you find your second gtx770? I was in the same boat as you was gonna SLi 2 770's. Ended up every where I looked the 770 was same price or close to the GTX970. So the second thing I think Oculus rift consumer version specs was calling for a GTX970. not for sure will hunt down the specs for that to verify...

Abburo Posted July 21, 2015 Share Posted July 21, 2015 If your GTX770 is the version with 2Gb then just switch to newest 970 or something. Do not buy the second one. If you have 4Gb video RAM then with a SLI configuration you are safe playing anything 1080p full details at super FPS rate.

I don't see why you would want to use the frame buffers independently. The reason that SLI right now mirrors the VRAM is because pulling files from one card to the other would increase memory latency enormously. Video cards rely on being able to access information very quickly. I would think that unless you are maxing out your frame buffer, you would only decrease your performance.
