I'm waiting till the 5830 comes out to buy any of these cards, but I'm wondering which would be best to buy for over clocking? I figured if I get a brand of one of these with a decent heat sink on it, I can really up the performance.

More about : 5750 5770 5830

Everyone here says wait for the 5830. Personally I would say go with the 5770. Who knows exactly when or in what price range/quantity the 5830 will actually be. It could be a $250-275 part. You can purchase a 5770 and overclock it, it beats the 4890, and in crossfire it beats the 5870 (which currently costs $400, where as the 5770s go for 150. If you have a motherboard which supports crossfire, you will get way more bang out of the 5770 in the long-haul. Crossfire seems to be picking up momentum as more companies adapt the multiple GPU strategy.

In my opinion, it is never wise to spend more then $200 on a GPU which are updated every ~8 months or so, and if you are an bi-yearly upgrader - Midrange is top, which is what the 5770 is.

I currently have two 5770s overclocked by 300MHZ on stock and they don't go above 49 degrees. They are a very cool, energy efficent card, and I imagine over time people will find a way to make a 5770 have 5830's performance, whenever we actually know what it is.

It also depends on your screen resolution. A 5750 would be good for 1440x900 and below, 5770 for 1680x1900 and below, 5830 for 1920x1080. You could get away with 5750 on 16x10 and 5770 on 19x10 but you will have to lower your textures and AA/AF much sooner rather than later in my opinion.

As long as you are willing to spend anywhere from $225 - $260 for the HD 5830 then wait. If that's too steep then just get the HD 5770.

If you do not consider $260 to be too steep, then you should actually tack on another $40 - $50 for the HD 5850 for better performance.



Hmph... didn't realize the HD 5850's price bumped back up above $300 until I did a price search. glad I bought mine for $280.

The HD5830 is based on the same processor as the HD5850/70. Both of those allow you to bump up the voltage which lets you OC like crazy(1ghz+)

Will a 21 amp 450w power supply work on a 5750?

Are you serious?!!!

EDIT:
I see what he meant now.

I consider 1GHz+ as 1GHz more.

i easily hit 1ghz on my 5870. no idea how the 5850 does with the same clock tough. and i imagine the 5830 will be even less likely to hit those clocks.

Im sure ATI will limit the 5830 from overclocking to much, like putting a 128 bit memory bus or DDR3 to name a few. They would not want a situation like "why buy the 5870 when you can overclock a 5830 for half the price" Just like the i7 920 vs the $1k i7 965.

well im pretty sure it going to have way less SCs. it doesnt really matter how high you clock it when it has a quarter of the SCs as the 5870.

same as with the 5850 and 5870. yeah the 5850 is great, but overclocking it doesn't make up for a a lack of hardware.

HD 5830 are likely to be HD 5850 GPUs that failed to pass validation. Thus some internal components are deactivated and "binned" for a lower grade GPU.

Selling these "failed" HD 5850 GPUs as HD 5830 GPUs makes sense since AMD is not simply throwing out those GPUs like trash. Thus wasting money.

yes, thats how it works. you didn't think they had made a whole new chip did you?

the 5850 cores are just binned 5870 cores. 5830 cores will be the ones that couldnt even be sold as 5850's.

hence why they will have less SCs and why no amount of overclocking will put them on par with a 5870. i still expect them to be very good, but only within the confines of their market. no OCing will get them competing with a 5870...

ah, i see.

yeah, im pretty sure we won't be adding another 1000mhz to stock clocks any time soon.

I was thinking, if the 5830 was released, it would bring the price of the 5750 and the 5770 down. If not the 5830, the 5970 would do that. Putting the cards around a 90-150 range. What performs best currently? 2x5750s or 2x5770s, ratio wise from single card. Also is there a big architectural difference between the 57xx and 58xx series?

That's not going to happen. The average price of the HD 5770 at this point in time is around $175 and the least expensive HD 5850 is about $305. That's a large $130 gap between the two cards, plus the HD 4890 is selling for around $200. The HD 5830 will be faster than the HD 4890 and my guess is the HD 5830 will sell for $230 - $260 on initial release.

2x5750's can perform better than a single HD 5850.

2x5750s are like a radeon 5850.
2x5770s are like a Radeon 5870.


Either way with crossfire of either card you should be set till its time to trade those up for the 6870 or 6850.

Not on that MOBO however you can buy Xfire mobos for under $80 these days. The one I currently have is $71 open box on newegg (however its for AMD only)

You can use a single or even doube ATI cards on an nvidia chipset, you just cant enable crossfire with two or more cards.

Wasn't there some video posted with someone who got xfire to run on an nvidia board? Using two HIS cards or something. If I do need a new board, I will go for the whole kit and kabootle and upgrade my ram to ddr3 and my cpu to i5.

5830 would be my vote, rumors say that the 5830 OC'ed is about 5/7% slower than the 5850. Nvidia is about to release Fermi at the end of march so you might want to wait a bit for better prices =)

Final HD 5830 specs leaked
http://www.fudzilla.com/content/view/17781/34/
The leaked slides that surfaced up at IT168.com looks like a real deal and the HD 5830 should have 1120 Stream processors, 56 Texture units and 16 ROPs. The HD 5830 works at 800MHz for the core and 1000MHz for the GDDR5 memory paired up with a 256-bit memory interface. This is slightly off from the early listings we came across some time ago. The one thing that caught our eye is the maximum board power consumption that stands at 175W, which is by 24W higher than on the HD 5850 (151W).

Case you missed it, ITS GOING TO use more power ? MAYBE run hotter?, lol.... I wonder why? Maybe a bios that runs with a higher voltage ? Remember this part had trouble in validation a coulple weeks ago. I"m totally guessing with the voltage comment, maybe its the higher clock speed alone that accounts for the watt rating difference?
Heres some specs to compare:

I would save up for a HD5850 if HD5830 is a negative.

I'd probably just get a new Fermi if I was going to save up. I need something that can handle video at 1680x1050, my 9600gt 512mb is not doing it well, and I've already waited around 3 months just to make a decision to get an ATI card.

Supposedly the cheaper of the Fermi cards will be $500 and it remains to be seen what you will get for that money.
For 1680x1050 just get an HD5770, there's no real need for anything more expensive. When you do upgrade the system consider crossfiring for performance similar to an H5870.

Fermi will be overkill @ 1680x1050 unless you play Crysis/Stalker at MAX settings... But I doubt you are buying Fermi for any of those 2 games anyways ;)  ...

Get a 5850 and you will be more than fine ...

To all the people that say, "oh wait for this gpu, wait theres another one coming out you might want to wait for that one." you are all playing the waiting game, and there is always going to be a better. So just make a decision already LMAO.
