5670x2vs 5770

[superxion8]

im looking to get a new video card to play newer games on wich one would be better 2 xfx 5670's or one xfx5770 both r 1 gigabyte cards

 

[shrkbay]

5670s would perform better than 5770, but you might have issues with running them

 

[superxion8]

so i should just get the 5770 cus ive read about alot of problems with crossfire

 

[jjb8675309]

yeah def a better choice than 2 5670s

 

[jyjjy]

Yeah, how much do you have to spend?

If you can afford a single card solution with little performance decrease you should always choose that option as crossfire/SLI will always have certain compatiblity issues, will always create more heat, and will always need more powerfull PSU. If you can afford a HD 5770 I would go for that option, that also allows you in the future to crossfire that witch gives you the rough performance of an HD5870!. The gtx 460 however, is a faster carder than the HD 5770 so might be a better choice, unless of course if you motherboard is only crossfire compatible and not SLI.

What resolution are you gaming at? and what are your other specs

 

[shrkbay]

^no 5770 CF does not perform like 5870, it performs worse, in other stuff i agree, but GTX460's prices have increased and it cost like 200$ now , OP: what's your budget? resolution? other specs?

hmm well here is one example where crossfire Hd5770 performs pretty much to the same standerd as the HD 5870

http://www.guru3d.com/article/radeon-hd-5770-review-test/14

Far cry 2 1980 x 1200 8xAA

Hd5770 crossfire x = 58fps.
Hd5870 = 59fps.

And don't make statements on something I know nothing about xP

I meant * I don't make statements *

5870 runs only on few games like 5770 CF, in other it beats them...

 

[sammieboi100]

neither, the gtx 460s are so cheap right now youd be silly not to get one...or two.
but sli/crossfire just doesnt produce enogh rewards for the power consumption, price and heat. if you dont want nvidia then just stick with one 5770.
good luck.

 

[iam2thecrowe]

if your not an advanced user and dont want to tinker with ini files, settings, 3rd party programs to get crossfire working well, and then still have issues with some games, then you should get a single card.

GTX 460s? only SE and 768MB, which are more or less 5750-5770 performance, normal 460 cost around 200$ right now and is clearly one of the worst bangs for buck, the 6850 beats it and can be found for 150$ AR

GTX 460s? only SE and 768MB, which are more or less 5750-5770 performance

The GTX 460 768mb is about 25% faster than the HD5770(and less than 10% slower than the HD6850) and can be had for just $110 after rebate right now. It has impressive overclocking abilities as well.

[shrkbay]

^wrong, 6850 is 15% faster than 768MB GTX 460, and GTX 460 768MB is only 10% faster than 5770

http://www.guru3d.com/article/geforce-gtx-460-se-review/10

I agree it OCs well

 

[jyjjy]

http://www.techpowerup.com/reviews/AMD/HD_6790/22.html
That's based on 13 games and 2 synthetic benchmarks. It has the GTX 460 768mb as 24.4% faster than the HD5770 and 8.5% slower than the HD6850. Those numbers are specific to a 1920x1200 resolution with 4xAA applied but the overall chart furthers the point.

guru3D link does not agree with you, also if you look down here:

http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/37499-hd-6870-hd-6850-vs-gtx-460-1gb-overclocking-study-15.html

6850 @891 core is avg 15% better than 460 1GB and is OCed by 13%, 15-13 is 2% higher performance on 6850 than on 460 1GB, while techpowerup shows the opposite, and the reason is that on hardwarecanucks they did not use nVidia/AMD prefering games, while on techpowerup they did, and more nVidia...
also on Tom's was a review on 6790 where it was running head to head with 460 768MB not 7% behind and that's because techpowerup used nVidia favored games... Techpowerup made very unfair review by giving nVidia some advantage, i showed you guru3D link where 5770 was 10% behind 460 768MB and 6850 15% faster than 460 768MB, and also if you look at 6850's advantage over 460 1GB, which is shown on hardwarecanucks, and on the picture you posted, it shows that 460 1GB is 10% ahead of 768MB version, while 6850, as i mentioned above, is 2% faster *probably more cause OCing doesn't bring 100% gain* than 1GB version, 10+2 is 12%, means my "guess" was closer to truth than yours

with respect

Purposely leaving out games that are skewed toward Nvidia is actually unfair to Nvidia as there really are a fair amount of games that do so and people do play them so they need to be factored in. I think the games Techpowerup have chosen to use are rather representative of the gaming market as a whole. That said I'm not sure why you are claiming bias actually because of the three the Hardware Canucks review has the game selection that is most skewed towards Nvidia IMO.
The guru3D link you gave was to one game. If you average all the games in that review they have the GTX 460 768mb as 23% faster than the HD5770. I don't feel like doing the math for the HD6850 but I'll give you that their numbers do appear closer to the 15% you are saying than my "less than 10%."
The Hardware Canucks review you are reading entirely wrong I believe. That chart is saying the GTX 460 FTW card which is sold with a huge overclock is 15% faster than the OC HD6850 at 1920 with 4xAA, not slower. OCed numbers are interesting but not really appropriate to what we are discussing. Here is the conclusion of their recent HD6790 review instead because it uses cards all three of the cards we are discussing at reference speeds;
http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/42228-amd-radeon-hd-6790-1gb-review-19.html
It says the HD6970, at 1920 with 4xAA, is 5% slower than the GTX 460 768mb and 15% faster than the HD5770. So that's saying the GTX 460 768mb is 20% faster than the HD5770 basically. It also says the HD6790 is 14% slower than the HD6850 vs 5% for the GTX 460. The difference there is 9%. Straight addition/subtraction of the percentages with different baselines like that is actually mathematically incorrect but it should still be very close to the real numbers, maybe off by a percentage point either way, but in any case their numbers are quite close to what I'm saying.

i have bout 150 bucks to spend ona video card my new board is cross firecompatible im running a 9600 phenom quadcore oc to 2.5 ghz 4 gigs of ddr2 800mhz wintecch ampx ram 600 wattpowersupply and a bunch of fans and my power supply only has 1 pcie 6 pin connector if i were to cross fire 2 5770s could i just use a connecotr or would i need a new powersupply

 

[superxion8]

and my resoultion is 1024 by 768

Depending on the brand/model of the PSU you may or may not need a new PSU to crossfire HD5770s. At your resolution though you shouldn't even consider it. The second HD5770 would be a total waste until you upgrade both your monitor and CPU.
So just get one for now. Even one HD5770 will likely be limited by your processor in a number of the more CPU intensive current games. In fact if you would like to save some money you could just go for this GTS 250 which is a very nice deal;

With your current CPU and resolution I doubt you will see much difference at all between that card and an HD5770.

will a nvidia card work properly ina crossfireboard ? and im looking to get at least a 1 gig card as far as nvidia goes i was looking at the 550ti from evga but like you said that might be overkill

 

[shrkbay]

NVidia card will work, but SLI won't
