GTX 770 SLI vs. Crossfire (Possibly trifire) R9 280x

[Tabungalu]

Hello guys, first time posting on toms hardware, but I have an opportunity to get some R9 280xs at a great price.

I have been doing research for the past two days - comparing benchmarks between 770s in sli and crossfire 280xs - I still want more information before I plunge for the 280xs.

I currently have 2 670s for nVidia surround. I have 3 Asus 24" monitors.

I want to know if I will see that much of an added benefit from going crossfire with 280xs. As the 3 gb of vram seems to be advantageous for eyefinity/surround. For the price of 2 280xs I would be able to sell my 670s and probably break even if not make a profit. But would it be worth it to go through all the extra trouble? Or should I not consider the 280xs and upgrade to 770s?

Also, how well do the 280xs scale in terms of trifire? Is it worth it?

280x is probably the best option, tri fire doesn't scale well

whether it be the GTX 770 or 280X or any card, having three or four cards in sli/cfire is just impractical and the scaling doesn't work so well unless your using 4-5 screens or a big 4k monitor. 2 cards in sli/cfire may or may not be worth it but tbh I would suggest getting the best single card you can get for the price of two 770s. Which is roughly a gtx 780 or maybe an R9 290X. Single cards offer more stability and scaling than you would with multiple cards. In most cases there's only a negligible difference depending on the resolution your running your rig at. All in all if I were you....

I'd get a GTX 780 or R9 290X most preferably the R9 290X because of the extra GB of RAM which could be useful for that triple screen-setup of yours.

P.S. I wouldn't put up a poll neither, your gonna really want people's opinions on a question like this. A poll wouldn't suffice. You need to see the odds and ends of both the cards and how well they scale plus the consideration of a single card

depends on what you do, as a whole dual R9 280X is the best way to go.

i think you should just keep that 670s for now and upgrade into next gen card (DX12) sometime next year.
