Hello everyone,

I was hoping you can help make my mind up for me.

For the price of ONE ATI 4890, I can get TWO 4850 which I can use in CrossFire. Looking at the benchmarks, two 4850's in CrossFire destroy an ATI 4890 (even when overclocked to 1GHz), nVidia GTX 260, 280, 275 and 285.

I have a 512MB 4870 at this moment in time and see no point in upgraded to a 4890 for a 10% performance increase when Crossfire 4850 can give me about 40% performance increase, at the SAME price as a single ATI 4890.

My problem is that I have heard so many nightmare stories about CrossFire regarding installation and in game problems. With this in mind, I want to stay with a single card solution. Would buying a 4870X2 bypass ALL CrossFire software? Is it seen as a single card in Windows and so eliminate ALL CrossFire related issues?

Ideally, I liked the Crossfire 4850 as Idle and Load power consumption is reasonable, whereas Crossfire 4870 and 4870X2 consume a bit too much power for me. Hence, why I am NOT going 4870 Crossife.

Any help is appreciated as I am looking to order asap.

Thanks.

With the 4870x2 you still have to worry about crossfire drivers.Best thing to do in my opinion is to get the fastest single card you can afford. There is always te option to go dual card in the future, but not needed. The 4850x2 is limited by its driver support from sapphire where the 4870x2 is supported by ati, but for both cards, if the game/application does not support xfire you are limited to one gpu. The 4850x2 on games that support crossfire should be on level with a gtx 285 and a 4890 oced.

Thanks for the quick reply, Chef.

The problem with the 4850X2 is indeed drivers but also noise. The cooler is one of the loudest out there. For these reasons, I have discounted it. Makes me wish I had an SLI board at this moment in time.

The 4850X2 should destroy an Oc 4890 btw :)

I guess it is better to buy something supported by ATI rather than Sapphire, hence the 4870X2.

If only the Nvidia 295 wasn't so damn expensive!
 
Well going with either 2 4850 in crossfire is a very good option now...but say in few months time, there will be newer games, which will be more demanding and if you want to upgrade, then you would have to replace 2 cards, which is a waste...
But where as going with a single powerful card make more sense as later you can crossfire them...and would be suffice for future games too...
And the 4870X2 is somewhat better...
But if you want to spend less money and get maximum performance, the 4830 crossfire is a better option than the 4850 crossfire...As these are very cheap, around $80 and 2 of them is around $160 and they can also beat nearly all the single-chip cards out there...

295 runs into same problems that a 4870x2 does. Only works correctly on sli supported games/software. The 4850x2 is about on par with an oced 4890 and gtx 285 at stock.You should be able to get a 4890 to oc to the performance of a gtx 285 and that is pretty much where the 4850x2 is at, might be a tad but etter on a few games. I still think you should stick with a 4890 or a gtx 285or 275. At stock it should trade blows with the 275 and oced it should be close or trade blows with the gtx 285. If you have a crossfire board i would recommend going with the 4890.

I'm sure that would be very funny in 5th grade.

Hello Rangers,

The reason why I do not want to purchase another 4870 is because looking at the idle/load power consumption, it is far too high for my liking. Especially idle where it sits at 285W. Not good when you use bit torrent so often.....

Yeah. The 4890 / GTX 275 are good choices. Due to no issues regarding Crossfire/SLI.

But back to the 4850, there are 4850 variants that use non stock heatsinks, and they work a lot better than the stock fans, like the Palit Radeon 4850 Sonic.
 
After the GX2, I will never recommend a X2 based card unless its a clear value, and the 4850X2 is not a value. Too much driver instability over time, and X2 cards tend to get phased out relativly quickly...

Not true.

I am not sure where you get these kind of ideas/ facts from?..... I can bet on my life that you've never owned a HD4850x2 card in your life... and thus rendering your advise useless... I really love when people just come up with facts like this...

It has been stated in previous forum postings, HD4850x2 and HD4870x2 have been officially supported by ATI from Cat 9.1, you can also check ATI's official driver documentation.

In future people that give "advises" pls double check your so called "advice" before stating it as general truth.

Concerning your question. 4890 it's still a great card, has lower power requirements than two hd4850s or HD4850x2, and when overclocked in some games it outperforms the hd4850x2. Also, you can always get another hd4890 in the future and crossfire it as need arises.
As of right now you'll do well in all of the games with just a single 4890. So go for it purchase a 4890.

Here is a nice benchmark by xBitlabs: http://www.xbitlabs.com/articles/video/display/radeon-hd4890.html

Cheers and have fun gaming!
 
Don't get a 4850x2, just get two 4850s.

If you plan to upgrade i the future for DX11 or beyond, get two 4850s.

If you probably won't upgrade for DX11, get the 4890 and upgrade to 2x4890 Xfire in the future.

Single 4890 or just keep what you have. Dont waste your time with crossfire, or even SLI for that matter, espically if you dont really need it. I promise you wont see the difference, I personally dropped a 4870 for 4850 crossfire and regretted it every single day until I got rid of it.

I don't understand how 4850 CrossFire was worse than your 4870? The only conclusion I can think of is that you must have had games that were not CrossFire compatible...?
 


suck ballz as in the drivers aren't from ATI itself, so the software support for the 4850x2 is piss poor

Yeah I wont argue there :)
Although their newer cards come with updated BIOS that keeps the fan at low rpms when working in 2d/Desktop, when gaming it's a different story... The fans do make a lot of noise.. I wish they redisigned their cooling, and went with some kind of aftermarket solution like Artic-Cooling has for the 4870x2. The small fans and high rpms it's a a big NO, NO for quiet cooling.
