considering going 4k 280x xfire enough?

[233]

as above i'm thinking of going down the 4k route for a bit of gaming improvement over my current 1080p


currently running a single 280x which never seems to struggle no matter what I throw at it.

would a second 280x added in crossfire be enough to drive a 4k panel at 60fps for most games?

Simple answer, nope!

It would be possible, but expect to be turning down settings regularly to achieve 60fps.

Dual 280x not enough crikey

What would I be looking at 2x290x/780ti?

4K is pretty demanding to drive - in BF4 with the settings I use (mostly ultra with a small number of sacrifices) my FPS plummet from an almost constant capped 125fps (meaning its generally 125 and above) to fluctuating between 60-70fps on a single 780.

A lot of the hit of 4K is fillrate related so to some degree CF and SLI help there as fillrate scaling tends to be one of the most efficient parts of multi GPU but you will probably bump the VRAM headroom at times as well - I know I do on my 3GB 780, in games that don't support CF very well though your going to see performance drop out massively.

290 crossfire/780 ti SLI is the lowest I would go for 4k personally.

I get good performance generally on a single albeit fairly heavily OC'd 780 aslong as I stay away from 4+x MSAA (not really too big an issue with 4K on 28") and occasionally have to turn down settings that hit the fillrates hard from ultra to high. Granted I'm going from often able to get around 120 fps ish to around 60fps ish but thats still perfectly playable for now.

Depends on the game I guess. I wouldn't want to try Crysis 3 or Metro at 4k with one 780.
For something like BF3/4 it might be okay.

IMO if you must go 4k now (and it isnt ready for prime time) I would go for SLI 780 6Gb cards.

Or two 290/x's.

There is little point going 4k and having a single card, as you wont be able to push the frames to justify the resolution.

We really need to see what the next gen cards form Nvidia and AMD can achieve.

I think if I was getting a new monitor I would get a 1440p/1600p until 4K matures a bit. 2 280x would cope with that pretty well.

TBH I've not tried either of those 2, pretty much everything else I've tried gets perfectly playable fps albeit not the kind of fps I'm used to with 1920x1080 120Hz gaming.

2 x 290 / 780.

2 x 280s will suffice if you're prepared to turn more than the odd setting down.
