Your gpus are holding on for dear life there.. why not try upgrading to say a 7970?

so the cards are weak fore 1440p even in crossfirex
so yes is best to get a radeon HD7970 ore a nvidia 680
thanx fore the answer

2 7770's is absolutely not enough for 1440p... You are not getting stuttering, your frame rates are just very low, most likely.

at that res, you might want to crossfire or sli to get closer to 60fps. A 7970 or a 680 both barely get 40fps in most games at 1440p. So ethier a 7950 crossfire(i recommend) or a 670 sli

You need a card with a lot of grunt and a lot of VRAM I've had bf3 using 2245 mb in game at 1440p

ty all fore the reply

but what is more inportend more mem ore more graphics power
the problem is that i get whit some games 40 a 60 fps whit stutering
i dont play fps games more like WoW SWTOR ore world of tanks games like that

on amd site the telling this

Graphics horsepower is moree important, but at that res memory and the memory bit bus also becomes a bigger factor though still need the power to handle the games.

You need to learn about how companies advertise.. yes the 7770s can DISPLAY 4096x2160p res. BUT AMD never said anything about playing did they? They say it can do this and that but really they show you what the max it can do without playing games to make it look more powerful.

You need at least 2x 7950s or 2x 670s to get over 60fps. wihth the games you play i would look up some benchmarks and try to see which cards they perfer, like amd or nvidia. Then choose the top range card from ethier company.

ok thanx than now what to do now
ok amd make pure markenting fore there chips
i will look up the benchmarks
thanx all fore the info

Please take a nice comfy seat and I will tell thee a tale.

Basically there isn't a single GPU card in the world that can put out the max settings in very modern games at the resolution you run with lots of MSAA.

Thus, when you absolutely depend on Crossfire or SLI your hopes will be dashed.

I once ran 5770s in Crossfire and it was an absolute nightmare on account of me depending upon it as one 5770 alone was not enough for the high settings and when Crossfire did not work or scaled incorrectly I had to reduce settings.

This is why I always advise those who want to run multiple GPUs to either do it properly or not at all.

By that I mean if you want to run a silly resolution like the one you are running then for god's sake make sure you do it properly. Buying two el cheapo cards and hoping they will be enough is absolute madness. If you were on a budget you should have budgeted for a high end GPU and then added another at a later date.

For titles like BF3 firstly you need more vram than you have, but secondly you need far more horsepower. One GTX 670 is not enough for that resolution with any sort of FSAA or MSAA and you would need two.

I personally would sell the monitor and buy a decent 1080p larger screen (they do them in 27" for a reasonable price) and get a GPU with some actual horsepower, not a pair of rubber bands.
