How good are the ATI 5750s in crossfire?

As title says. I cant seem to find any benchmarks for these in crossfire :( you think 2 of them can play every game at 1080p with atleast 30 fps?
 
I have them in crossfire and i find them good.
Only have them clocked at 775/1200 as mine are poor clockers :(

If their is any benchmarks u would like me to run, and if i have them i will (keep in mine my res is 1680*1050)
 
thanks for the link maddness :D thats convinceing me to get them. Aslong as i get atleast 30-40fps on 1080p for less than £200..ill be happy!

do they have the voltage tweaker version like the other cards?? have you tried msi afterburner with them??

No you cant tweak the voltage using any program. But would have to mess around at the back doing some sort of mod to the card. I flashed mine with the Asus bios 5770. And could tweak the voltage. But after much trying even though it was showing that my voltage had gone up, infact it was still at default (so it did not work). Also i could not get a better overclock.
 
Everyone seems to complain about the 5750s, because of the few reviews out there, but I've got one for my brother today as his xmas present, and I have to say Im pretty impressed.

He's got the XFX one, the ATI autotune seems to take an absolute age (stopped it earlier after an hour, was just testing thoroughly it seems as it had finished clocking the core and was testing memory at this point), so we're having to wait to see what the ATI drivers think is stable, however it seems like his card is good for 860Mhz and 1300-1450MHz (GDDR5 but 128bit link so actually works out about that compared to GDDR3) on the memory. Pulled out a vantage GPU score of 9100 when I set the overdrive temporarily to maximum [which actually seemed fine heat and stability wise, but I'd rather let the autotune decide what it wants to do, as it actually seems to be stressing it properly rather than as a quick 5 minute job], which is higher than my 4870 used to be, and on top it runs cooler, a bit quieter and uses less juice.

If most of them overclock reasonably well, then you're looking at something damned close to the 4870 or 5770, for about £85, with added eyefinity and dx11 support. Crossfire them and I can see that being the sub £200 gaming setup of choice, as power usage is pretty low, they're small and they go!

Stock GPU score in Vantage is 7500 approximately, so it shows just how much juice they've got in reserve if you get good ones. Two decent overclocking cards would be perfect for a decent gaming machine on the cheap, I've actually suggested he looks into buying another if he can pull something similar out as he'll have a machine that'll last a good few years, pretty cheaply :)

As a reference, his old card was a 9600GSO. As it stands, from what we've seen so far, this card is virtually 140% to 200% the speed of the GSO...in EVERYTHING, even at stock,and is about another 15-20% faster overclocked.

Alexrose1uk i agree with you. The 5750s are underlooked and seen as a budget card. But really they are good in the guru3d review!

Theres a video on youtube of HAWX playing on 6 monitors 1280x1024 maxed out completely and getting 30fps minimum...thats just 1 card! for £87..i find that quite astonishing!
 
Thats a nice overclock Alexrose1uk.
I find that i can push my cards more in some games. But other games will crash on me so i need to turn the clock down. In the end i found 775/1200 stable in all games. If your 860/**** clock is stable in all games then that will be sweat.

My 2 cards get 15,353 points in 3dmark vantage, i was running a clock of 840/1225 in that benchmark.

the £85 ones are the 512mb editions am I right? the problem with the 5750 1gb is that they are too closely priced to the 5770, for the extra £8-£10 you would be crazy to get a 5750 1gb over a 5770 1gb ....to save a few pounds, 80 extra shaders and 4 extra texture units as well as the higher clock speeds is worth the £8 in anyones books :p

the 5750 needs to come down in price to sub hundred to make it a good purchase.

So if i ever had to purchase 2 cheap cards till the nvidia cards come out. I would be best to go for the 512mb versions ?

The autotune finished after about an hour and a half...decided 860/1420 was stable, was much slower testing than I remembered, so at least it heated the card properly etc, last time I used the thing with my 4870 it took about 2 minutes, and didnt use the full screen image, so I guess they decided to revamp that! :)
9050 GPU score in vantage (P mode). I know the 9.12 drivers have offered performance boosts in vantage, but still, that's roughly on par with my old 4870, and at £85 it's cheaper than a new 4870 too (with added features)!

I dont disagree that the 1GB version is a little too close to the 5770, but hello, there's a 512MB version too, if you're trying to save money and use a slightly smaller monitor it seems to be a perfect card! From experience of my old 4870, I can also say very few games were unplayable at 1920x1200! Only one that I played that REALLY suffered from texture memory restraints was Stalker Complete Mod 2009, maxed out at 1920x1200, so these things seem perfect for someone playing at 1680x1050 or less, especially if its a good clocker.

My brother is over the moon coming from a 9600GSO, the performance increase from a 'budget gamer' card is staggering!
At £85, it's also sufficiently cheaper (£35+) than most 5770s to give it a decent market position. Hell, even at 7500 GPU score stock speeds, it's not a bad little card, but I do think 7500-9050 GPU score shows there is a lot of overclocking potential sitting in a lot of these things, especially as it runs cool anyway. I'd guess they were 'restricted' to stop them catching up with the 5770s so easily!


PS Marc, like SLI, Crossfire only uses the effective memory of 1 card (ie 2x 512 is treated as 512mb as both cards need the textures), that said 2 of these (especially overclocked well) should play anything at 1680x1050 or below VERY nicely.

5850 is more consistant but £230, two of the 512MB 5750 cards are £170. If you're not texture memory limited then overclocked 5750s are pretty potent. Going by the Guru3d review, these aren't far off the 5850 when they're crossfired at stock [and sometimes beat the 5870 dependant on the game], throw in hefty overclocks and you're onto a winner if your screen size doesn't cause bottlenecks!

2 512MB cards is still only 512MB as both cards story the same data.

The reason that the 5750 are overlooked is because the the 1GB version is only £5-10 cheaper than 5770, which is ~20% faster. The 5750 512MB is better value, especially if one is playing at 1680*1050, or less. Also note that the review is using the 1GB version, not the 512MB.
