They are the same price @ $260, but I have not seen any direct comparisons.

More about : 4870 4830

Depends on the games you plan to play, and the resolution you are using, but seeing that two 4850's in crossfire are neck and neck with a 4870 I think you'd be safe to go with a single 4870 instead of two 4830's.

Get the 4870 that would leave you an open slot incase later you deside to go Crossfire with a second 4870.

+1

Forward thinking for future upgrades is always the way to go.

LOL
No

CrossFire 4850's will PWN a single 4870.


Op, it is hard for me to recommend for sure either way.
Cf 4830's will probably beat a single 4870 in many games but I have not yet seen any Cf benchmarks.
I am leaning towards a single 4870 as being the proper choice for you.
It will give you very good performance and, if it is not enough, you can always Cf it down the road.
With just one more powerful card, you will also avoid all the potential performance drops inherit to a multi GPU solution.

Single Card. Not every game is developed for multi-GPU setups. They have to be optimised for it durring developement. Therefore, you will see consistent good performance from a single highend card.

Well, there aren't any direct benchmarks of dual 4830 to 4870, but the 4830 performs basically the same as 8800gt...

...and dual 8800gt blows away a single 4870...

...so it would be reasonable that dual 4830 would far outperform single 4870.

Not to mention that since 4830 use a crippled and downclocked high end core, which means high overclocking headroom, while 4870's core is already clocked near max, which means lower relative oc headroom.

So if they cost the same, dual 4830 would be the way to go over single 4870.

Also, despite what many people say, there is nothing wrong with dual gpu, either in the form of dual cards or x2 cards. All new games scales with dual gpu. Old games that do not already get hundreds of fps on single gpu that it doesn't matter anyway.

If I were you I would get a single 4870 or dual 4850.

wow camulus couldn't be more off... now i know not to take that dude's advice lol

yeah i would personally get one card over two, it should consume less power overall, and less scaling consistencies you have to worry about.. so one 4870 ftw[asus top with aftermarket cooler is like $219 AR]

and the saphire card is really cheap now. I have it and I'm very happy. No problems (I play many games) whatsoever.

It's a good thing I have no idea what card you are talking about. I'd hate to be able to understand what your contribution to the conversation might be. What card is this? 4870 or the 4830? or the 4850? or some pretty playing cards?
October 30, 2008 2:18:45 PM

blashyrkh is talking about a 4870 like the guy above him
October 30, 2008 2:38:59 PM

First of all... thanks for the input. I actually expected it to lean more heavy to the crossfire solution. It gives me more to think about. As far as a few of the comments...

I am just looking at the here-and-now. So thinking of adding another 48?? later is not in my thinking, with directx 11 coming soon enough.

My applications utilize dual+ GPU

I do care about noise, heat, and power consumption, but only to a point.. and in that order.

So far with no real tangible facts I am getting the impression that the 4830x2 would be better performance at the cost of another slot, and power, and maybe a little headache in configuration. And the 4870 is the simple solution, not as powerful, uses less power (probably), but allows use of the other x16 slot.

eklipz330 (and others), check out Tom's Gaming Graphics Charts for Q3. There you can see that in some games the 4870 takes the lead, in others two 4850's in CF.

C'mon Calumus, you don't impress me with your reasoned contributions and your fancy back up. We all know you are a crack head! :pt1cable: 

If we are really interested in Duel vs single, then why not skip the 4830's to begin with? If you can afford two cards, then the jump in price to a 4850 from a 4830 isn't that big. I could see not wanting to jump from duel 4850's to 4870's, but this really isn't a huge leap.

That's the right answer. You will be much more satisfied with a single card at the same performance level because you won't have to worry about crossfire scalability or any games without a crossfire profile.

Not looking at the performance issue, Not sure what percent gain loss for 2 4830 vs 4870.

But from a standpoint of Lost heat ( added heat into the case ) and from a standpoint of air flow in the case I Would opt for the single card. While the 4830 will generate less heat than a 4870, I think 4830 x 2 will pump more than a single 4870. Think of a two 25 watt lite bulb vs a single 40 watt lite bulb. Will get more lite from the two 25's BUT also more heat.

Looking at newegg, all three 4830's are single slot cards exhausting the heat into the case vs a 4870 daul slot card sending a good % of heat out the back of the case. A single card will alow better airflow within the Case.

A single 4870 would be sooooooooo muuuuuuch simpler then 3x 4830's. You sure you know what you're getting yourself into putting 3 hunks of gfx cards in your machine?
Just keep it simple...
Or if you want to go complex get an x2...
