2x 4770 Crossfire for 1920 x 1080 resolution?

Will 2x 4770 Crossfired enough for 1920 x 1080 resolution?

I'm currently using 1x 4770 and I'm going to get new LCD [Samsung 2333SW] and I would like to know if 2x 4770 will be enough to play on resolution 1920x 1080?

One would be enough for most games, and two would be fine. But I would get a 1gb card(or two) if I were you however. I've had many 512mb and 1gb cards at 1920x1080 and the single GPU 1gb's produce a much more stable gaming experience.

when using xfire only one of the cards ram is used so if you are using 2 x 512mb cards then it will only use 512mb but for over 1200x1024 with aa and af you need more than 512mb as you will run out of frame buffer at those resoluitions.

 

[aquax]

it is better to get 4890 instead?

 

[ShadowFold]

IMO Yes

 

[erocker]

4890 would be better for that resolution for sure.

I was using reference 4870 1GB and I wasn't happy with it, temps were high and the fan was very noisy, does the reference 4890 still suffer from this problems?
4770 is really good, runs very cool, max temp 60c with furmark stock cooling and fan @ 35% and gives great performance, can't see difference between it and my previous HD4870 @ 1440x900, but I'm going to upgrade to 23" LCD, I thinked to get another 4770 and make crossfire but seems it won't be good with an 23" LCD

The reference coolers are loud. Loud on the 4890 and loud on the 4870. Get the Toxic version, nice high clocks and a beautiful cooler that is not loud.

toxic is still not available in my country, what about the power color 4890 PCS+ with ZeroTherm cooler?
do you suggest to get first my new LCD and test my games with the HD4770 and see how the performance will be?

Don't know if its the same zerotherm used in older 3800 card's, but if it's the same it's really quiet.

I know what you say there is true but think you have gone abit ott. I have two gaming pcs & run them on big high spec crt monitors. One with 8800gt 512mb @ 1600x1200 the other has a HD4850 512mb @ 1800x1440
. I still get good frame rates with crysis, cod 5 & alike.

1 4770 works fine on my 1920x1200 monitor...
and 2 works better, but if it all depends on what games your playing and the settings you use.

but if your willing to spend some extra cash on a 1gb card, it may be better for you.

1 4770 would be fine to run 1920 res . . . but, that depends on how well you want a game to run. Depending on the game itself, and how GPU intensive it is, you might not be able to run high quality settings . . . if you're fine with that, then it's entirelly up to you . . .



Still not sure why people complain about the heat output and noise of the 4870s . . . TBH, they're some of the coolest running cards I've ever seen, and the noise isn't overly loud or distracting . . . unlike the coolers on much older VGA adapters . . .
