In about a week I'm going to pick up one of these, Just want some input if going the 4870 is worth the cash .found http://www.tigerdirect.com/applications/SearchTools/ite... after rebate 165 for the 4850. If you can find any rebate deals ect. plx post.
How much better is the 4870 to 4850?

More about : 4850 4870

Both the cards are VERY worth their price... although the 4850 gives better bang for buck, if you can spend $300 then 4870 is definitely a sexilicious buy.... in the below benchmark 4870 is behind the GTX280 by only one and a half FPS for Crysis Very High 1920 res.

Also check the benchmarks of other games in that review...depending on which games you play you should get whichever card seems worth.

If you have a CF mobo 4850 is a better deal since there isn't that much difference between 4850 CF and 4870 CF.

Make sure you have a good PSU.

of course 4850 best value for money

Thxs, I'll get 4850 Thinking near future to upgrade again like in 6 mounths save 30-40$ a mounth and bang :wahoo:

Both cards are great. I went for the 4870 for the dual slot cooler and better performance, but the 4850 gives you the best bang for the buck. Both cards overclock really well if you turn the fan speed up a bit.

The dual slot , the higher fps which in total is over the 20% core difference Its by far the better card. Worth an extra 100? Im getting one. Mainly its because I want that heat out the back of my case, not in it. Plus, I wont have to upgrade for awhile again

I may get a 4850, but I'll wait for a better cooler.

4870 - FTW

Not that I am bias, or that I just got my HD4870 yesterday and it clocks out of the box with CCC to 790 core and 1100 memory with only a 2 degree increase in heat at default and by setting the fan speed to 40, it runs a nice cool 42 degrees at 100% load.

Other thoughts and impressions now that I have the card on hand, its heavy and large. I also have not noticed any artifacts or shutter running Mass Effect, Supreme Commander, COD4, Oblivion, NWN2, LOTRO, or any other game I have tried, currently running at 1680X1050 4x AA 8 x AF (silky smooth frame rates).


But the 4850 is the better bang for the buck.... but my Bucks just needed a better BANG.

What program are you using to set the fan speeds?...also what are you ramping them up to?
July 11, 2008 11:51:53 AM

How about the super R770?? It's supposed to be an awesome overclocker with core speed reaching the 1Ghz mark!! When is that @#$% coming out?

Once again this was shamelessly stolen for another forum and edited as needed.

Make a new profile in catalyst after turning on Overdrive (make sure your clock and memory settings are at their default settings), make note of the profile name. You can then go to the file "C:\Users\yourname\AppData\Local\ATI\ACE\. You will have to go into folder options and turn on hidden folders if you can not find the AppData folder. Once there look for a xml file that will have the same name as the catalyst profile you saved. right click and hit edit.

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Automatic" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="16" />

Change the value from "Automatic" to "Manual" in the first line in bold above

and Change the second bold lines Want value to "60" (or what ever setting you would like to try... don't go below the setting thats already there)

Save the file then reload and activate your profile in catalyst.

Setting the fan at 40% worked perfect for me, that said at 70% it was pretty loud but you may need to set it that high if your case has poor air flow.

You may have to select the profile every time you start the computer, but it will work until there is a fix or they release the 8.7 drivers.

They are already out they are called HD4870 (you just have to get lucky), the super R770 are just a unlocked bin and have a bit better cooling, ATI had a lot of higher grade parts, so they just made a different SKU.

I have a already set my card (Basic HD4870) up to a 970 core with a utility that allows the card to go around the CCC lock. The only issue is the utility only sets one clock setting, so sitting at you desktop in 2D it still runs at whatever you set. Most I have gotten out of the memory so far is 1285 but I think its a cooling and voltage issue from there, I am pretty sure you can and will see higher.

That said until you can set the card with both 2d and 3d settings I will stick to a CCC overclock, there is no need to running the card full blast at 100% of the time.

Where can I find the super R770?

Well said.

Currently here http://www.smoothcreations.com/ for a Super R770 is only place I know of, they are suppose to hit the retail chain soon.

But as I stated above I think quite a few 4870's will hit close to it when you bypass the CCC lock on overclocking. Just make sure you turn up the fan before going to high.
July 11, 2008 12:27:52 PM

If you can afford the 4870 get it. The DDR5 ups the memory bandwidth quite considerably which helps when playing certain games or using anti-aliasing.
July 11, 2008 12:44:38 PM

The 4850 certainly does offer the most bang for the buck, because uot of the two it is more likely to actually go bang, or induce one of your other subsequently overheated components to do so instead.

There's keeping costs down and then there is being stupid. The reference 4850 cooling design is stupid. And unbelievably loud at anything over 40%. And 2 in Crossfire? The only place they should belong is on the grill at Burger King.

The 4870 improves this enormously. Unless you want to change the cooler on the 4850, which is then getting into 4870 price territory anyway, go for the 4870.

LoL
But very true.

The 4850 gives you a great bang for the buck. For the price of one 4870 you could, very nearly, have 2 4850's. That would be my recomendation. Cf 4850's will PWN anything currently out except Cf 4870's.

That being said, you will want to upgrade the cooling as they run VERY hot. Turning the fan past 45% is unbearably loud. Even at 45%, they still work in the upper 90's. Upgraded cooling is not overly expensive but it will raise the cost of your setup. The Artic Cooling AccelS1 Rev 2 runs about $30 and is said to work wonders on the 48xx's temps.
July 11, 2008 1:47:07 PM

Vis a vis... if you can spend $300, get the 4870.... if you can't spend more than $180, get the 4850. Its as simple as that. Both are great buys.
July 11, 2008 1:54:28 PM

I think one question that needs to be asked here is:

Do you have a CF mobo ?

if not, you might want to wait for the 4870x2

Lets throw that into the mix
July 11, 2008 8:20:50 PM

I don't have a crossfire mobo, I play wow, Tibia, future starcraft 2. I might see if I can wait till the x2.
