Single 5770 enough for Eyefinity??

[divertiti]

I'm planning on running eyefinity, and I don't really wanna shell out for a 5850. I can get a 5770 for a decent price, just wondering if it'll be enough to play games at 4080x768 (1360x768) with max details?
If it can run Bad company 2 maxed at that resolution I'd be happy.

Anyone have any experience with this?

Here is a link to a good review comparing the different eyefinity models http://www.hardocp.com/article/2010/01/05/amds_ati_radeon_eyefinity_performance_review/10

Here is a section from the article regarding the 5770:

Radeon HD 5770

The Radeon HD 5770 is what we would call under-performing for larger Eyefinity resolutions. Yes, the Radeon HD 5770 can run all Eyefinity resolutions, but in most games that is going to cost you a severe drop in image quality and thus the gameplay experience. Only in very few select games, or older games perhaps, the Radeon HD 5770 would work well. For example some older games, released 5+ years ago, might play very well on it at Eyefinity resolutions. Some newer games even like Left 4 Dead 2 also play well, but for the most part, it is underpowered for Eyefinity resolutions.

And in summary...

In summary, for Eyefinity gaming, most hardware and gaming enthusiasts do not want anything less than a Radeon HD 5850 with a resolution as large as 5760x1200. Obviously, lower resolutions with smaller multiple displays is going to give you overall better performance. Still, we think 5850 is going to be the "cut off" point for a great Eyefinity experience. If you can afford it, go with the Radeon HD 5870; it HardOCP’s preferred card.

Thanks, I've read that review already, the thing is they're using 5760x1200=6.912,000 pixels. I'm gonna be using 4080x768=3,133,440 pixels.
I'll be pushing less than half the pixels they did, so I can't really rely on their findings....

[BanjoDubz]

Well you can rely on it to some degree, cos for instance, halving the resolution may have more of an effect when you have limited memory available, where certain quality settings may not be attainable at all due to the lack of processing power.

There does not appear to be a be a good review on the card at those resolutions however.

[Sideeffect]

I think you should save up for the 5850 if you want to run eyefinity with decent settings. The 5770 although a decent midrange card is not as fast as the last generation 4890. It has limited memory bandwidth which is going to hurt at high resolutions.

If you check this review http://www.guru3d.com/article/radeon-hd-5770-review-test/14 you can see the FPS taking a huge hit at resolutions above 1920 x 1200.

What monitors are you going to be using? I'm testing the 5770 now. I'm finding that Source Engine games still run great in 5040x1050 and 5760x1200, and even the Far Cry 2 benchmark hits 24 and 20fps respectively. And these are all 4xAA with max settings. Can't figure out BC2 would run (don't own it), and my monitors won't go to that low of a resolution.

I'm running a 32" LCD TV and a couple of Acer LCDs on the side. I'm pretty sure any monitor would be able to do 1360x768, but I guess because all of your monitors are capable of higher res, eyefinity won't let you do 4080x768?

Ibrin are you going to do a full benchmark review of the 5770? Or maybe some comparison benchmarks to compare it to the 5870 eyefinity in your other review?

Are ATI going to send you an eyefinity 6 for testing?

i used a 5770 for 3x 1920 x 1200 ... it worked fine for most games like fallout and il2 and BF2 and borderlands.. no problem.. but you will be severely limited by memory you can only put max 2x aa in most games, and good luck getting shadows ect without a slowdown.. if you OC it to 950mhz and 1400 ram, that helps alot, lowering the resolution helps too but you will still be limited severely on aa and af, if image quality is less important to you then 5770 will be fine, probably underpowered in 2 years.. a 5850 / 5870 will give you probably much better quality and last longer, and most games will run smoother.. but its definitely and option for you

[noquarter]

I actually use my 5770 at 3840x1024 quite often which is pretty close in pixel count to what you're at. I can play Bad Company 2 at high settings and get about 28 fps but not really with any decent AA. I'm actually CPU limited, so you'd probably find it even more playable.

But it runs it well enough for me I'm not disappointed. I would prefer a 5850 for AA and 5760x1080, but my plan was to get a 5770 until I could afford another 5770 to CF since I had to buy monitors and still need a new CPU.

My framerate chugs in certain areas in Borderlands with a 5870 at 3x1920x1200. Most of the time though it stays in the 30s to 40s. That's with all in-game settings maxed.

If you're wanting to do Eyefinity be aware of a few things with the 5770:

1) You MUST have either a DisplayPort enabled monitor or an ACTIVE DisplayPort to DVI adapter, a passive adapter will not work. Expect to spend at least $100 for this, up to $150.

2) Because of the 128-bit memory bus on the 5770, resolutions higher than 1920x1200 in Eyefinity, no matter how many cards you add, will lag.

3) Because of the lower-powered processor, to do res higher than 1024x768 in Eyefinity, you need 2 cards, minimum. I'm able to do 1920x1200 Eyefinity in BFBC2 with a mixture of medium and high settings, 2xAA, 0xAF, with 2x5770 in CFX. 3 cards can push max at 1920x1200 Eyefinity on pretty much anything, but 3 card Crossfire has issues with some games as well as weird problems in the drivers.

Had I known what I know now when I went to build this system, I would have got 2x5850 instead of 2x5770. I had thought I was saving $200 off 1x5870, but between the ACTIVE DisplayPort adapter, and the amount I've had to tweak it to get it working how I'd like, the 5870 or 2x5850 would have been a better deal.

I posted benchmarks for the 5770 in my review of the 5850/5830.

For what it is worth, I'm running a single 5770 with 3 19 inch wide screen monitors and I love it.

I was able to play through AVP Dx11 and SupCom2 with i think max settings and I didn't think the card struggled.

Sure it prob could be faster and i prob could have spent more money but when it comes to money well spent, I'm glad i got an active DP to DVI adapter and two extra monitors rather than a second card for my single monitor. 3x1 is just impressive, even if it isn't the fastest.

I still intend to get a second card as soon as I've the cash, but it has not shown to be totally necessary to me yet. I'm suppose I'm only a casual gamer.

I'm using my single 5770 with 2 X DVI and 1 X DP to VGA(Startech $25). Works perfectly fine with 3 X 1920X1080 Monitors.

With a Good processor the 5770 is enough for a lot of games. i run bad company 2 at 4320x900 max settings hbdao or whatever off 2xaa with 40 fps avg, but thats in dx11 which i get better fps in anyways.

[Dyre Straits]

XFX HD5770 is what I'm using.

[bmac6996]

I have a XFX 5770 Also. I play World of Warcraft in ultra settings fine. (except in Dal of course)

I tried Crysis Warhead.. if I have it under "gamer mode" it bogs to about 20-24 FPS.. if i select "enthusiast" setting.. i get above 40 on average.

[jimbo75]

A 5770 is great in eyefinity for me, 5040x1050. I do have it overclocked, and my phenom II cpu too.

It's not perfect but if it were nobody would buy the faster cards. I find lowering settings works fine, especially AA which is imo pretty overrated past 4xAA anyway.

[Gimpylung]

All the vids I posted here were on a 5770 with a very conservatively overclocked Q6600(2.666) @ 5276(bez) x 1050

Like Jimbo said, tweak the game settings a bit and most games run just fine...
