Pondering over an SLI upgrade

[Phunky]

So i'm hovering over the buy button for a second 670 and a new motherboard to go SLI but i'm not sure if i'll really see the benefit in performance for the cost.

I game at 2560x1440, 1920x1440, 1080p depending on performance and type of game (CSGO @ 4:3 ratio) and like to see 80fps+ at least, but I also like to pump up the graphics.

I'm worried I won't see a good enough performance boost for the £300+ cost.

A second card at 1440p will help. That res can be demanding, so a second 670 will help.

Whether its worth upgrading you're motherboard for is a tough one..

Are you seeing bad FPS at the moment? or just got the itch?

My mobo doesn't support SLI otherwise i'd have jumped ages ago performance is ok for most games so it's certainly the 'itch" that is driving this.

Things like Dayz struggle at @1440 but then I don't think SLI helps either and for other games I play I do get more than good enough FPS.

My gut feeling is that it just won't be big enough of a boost in most games I play and i'll regret it. Should just wait until prices drop more.

Having an extra GTX670 to SLI with would definitely helps a lot for 2560 res...but the most important question is- do the games you play scale well with SLI?

Take sources games for example they are generally poor with multi-GPU and offer bare any extra performance over the single card (not that a single 670 would struggle to do 60fps in those games at 2560 res I think), and lots of mmos etc don't benefit much from mult-GPU.

So it might worth doing some research on the games before deciding to go ahead of not.

CSGO runs at 130~300fps depending on map at 1920x1440@120hz and pretty much the same at full res.

Grid 2 runs at 110~160fps at full res.

BF3 can struggle on high but can get it looking visually pleasing and running 100fps+ (no AA or AO).

COD:BOP2 runs 125fps+ with everything on full easy

DayZ 40~150 depending on config settings

Most games do run above 80fps or I can at least get them to run at that with minimal tweaks and this is why i'm struggling with the decision.

Getting this stops me getting a Nvidia Shield I think i'll go with the latter now after talking out loud with you guys.
