I agree that lower framerates are far more of a hinderence in online games like CS, but framerates that arent a locked 30 or 60 generally look/feel like crap on pc monitors. Even if you cap the framerate with a 3rd party utility. Gta 5 in particular feels worse than most titles. For this title gsync is a much better upgrade than a new gpu
Locked 42* fps feels a lot better than locked 30 for me. Looks better too... it's pretty smooth with RTSS. I use it to lock games even at 60.
I'll need to check out g-sync but my 780ti isn't the stud I thought it was when I picked it up, feeling the need to upgrade (got a free upgrade from amazon from last year that I've still held onto) but nothing reasonable out yet...
I was supposed to trade in this 4k monitor to go towards a gysnc 2560. I should do that.
*44 even, though I was playing on 42 for a while, which was better than 30 too.
