Graphics Card Update

[Issom Deluxe]

Sorry for what I'm sure is a repetitive question, but my searches never really helped me. 

Currently using a Del 8900 (i7 6700 cpu @ 3.4) with a GeForce GTX 745. I might add, I'm on a DSL connection (1.4mb down) which I know limits me, but I am curious if I upgraded my graphics card to a better model (modest budget) if I would see an improvement. If so what card would be a good upgrade to put in my 8900? Or given my connection just save my money?

And the only internet connection option I have is HugesNet, which I understand is still a poor option. 

 

Thanks for the input!

Going to guess it's this one here?
the low dsl speed will bottle neck you, since there is over head on that line,  1.4 down at the best of times, so taking into account of that you'll get mostly 600kbps down that will be stableish,  mm  now since we know that.  I would go for Nvidia 1080ti, I would avoid the rtx cards as they do not add much to things,  I'm running dual 980's personally and it's fine like that.

That is a newer model, mine is older with a 3.4 processor.
