So I was going to upgrade my 1070 to a 1080ti but due to the fact that nvda stopped production on them they are very expensive now and I am not sure if I should get one. At first I was thinking on upgrading to a 2080 instead because the retail prices are similar but then I had an idea. 1070 cards are very very cheap theses days and I was wondering if I should get a second one and just do SLI. It doesn't seem to bad of an idea because the cards are so cheap and I will also be getting value out of my current card. Some people say that SLI will only just make one graphics card work for some games but I mostly play overwatch, rainbow six siege, and some destiny 2. Does SLI work for those games. Anyway, if anybody has any tips on what I should do for an upgrade please let me know.
PS, is it worth getting computer parts on black Friday/cyber Monday
Thanks in advance
