So my GPU fried on my pre-built PC I had purchased from Microcenter about January of last year. I was using my roommate's old GPU from his PC for a while but it was constantly BSODing (gtx 570) so I decided to purchase a cheap GPU to use for now, a 1050 Ti.

Well, while laying in bed tonight I had an epiphany. Even if I bought the PC pre-built, I wonder if my GPU has a SN on it and a good warranty? I got the SN and found out the warranty is good and sent an RMA request.

So now I'm going to have a 1050 Ti with 4gb VRAM and a 980 Ti with 6 gb VRAM. I read that you can't SLI 2 cards with different VRAM on the Nvidia site, but then I have read elsewhere that you can. Would I be able to SLI these cards, and if I can, would it be worth it? Thanks!
 
Solution
To SLI, you need a SLI compatable motherboard, and you need two GPUS that are the same with the same amount of vram.

So no, you cannot SLI them two. Plus the 1050 ti doesnt support SLI anyway.

Thanks! I didn't know. Would it be worth to keep the 1050 Ti to use strictly for Physx?

Well on the physx note it kind of depends. I use a GTX 1050Ti as a physx card with 2 GTX 1080s in SLI for 4K gaming. That said I game at a very high resolution with max settings, manually set filtering/AA to 16x by 8x or better so I have games where having the dedicated Physx card in use is the difference between 45-50FPS without my GTX 1050Ti doing dedicated physx and a solid 60+fps using it.. Point being unless your already maxing out your primary GPU (GTX 980Ti) and unable to keep up the frame rate you want with physx enabled...it isn't much worth it. If you find yourself dipping in FPS in physx titles however, then it may be worth using. Regardless dedicated physx use is a niche group.
