5850 vs 6870 - Page 3

post #21 of 37
It would be wise to do some 3dmark11 result comparisons. Be sure to select the same processor type, then compare results of the two different cards. You may be surprised at what you will find, particularly when you look at the extreme preset results. The 6850 holds it's own against the 5850 in performance mode, and beats it handily in extreme mode when both cards are OC'd to 1GHZ.

Bottom line: 6800 series, while shader architecture is similar to 5800 series, is more efficient, able to perform more with less. If you are buying new cards, this is where to place your money.

5800 series cards are a good choice if you can get them slightly used, at a bargain.

God, some fabulous replies guys! See this is why i posted here, a shear fountain of great information here.

Ok so some clarification seems to be in order. Yes I do run a multiple monitor setup, but it's only two monitors. I play on just the one widescreen, my second monitor is generally for any extra programs i might be running alongside my game, like vent, or mumble etc.

So it's starting to seem that i need to choose between cross firing 2 6870s or just picking up the one 6950 and unlocking it (something i have never done before and am always leery about that stuff) to a 6970.

So money and up-gradeability asides, what are the pros and cons of those two setups? Cross firing 6870s and single 6950. What kind of performance am i likely to get out of each setup? So what is going to offer the better performance i guess is what i am after?

(And just for the record to the person wanting screen shots, i intend to make a work log out of this. This is a brand new build from the ground up. I intend to post pics of everything i do, including the arrival of all the parts.)

you will get more performance out of crossfired 6870s...but unless you wish to max out crysis or metro 2033 a single gpu might be for you...

not knowing your budget...high end wise 6950(unlocked) is the best ati deal...for the 5800 series...a 5850 at stock 5870 specs would work as well... all depends on what you want

I second this.

definitely 6870
post #26 of 37


they both scale pretty well in crossfire, but the 6870 beats it. those extra couple bucks will definitely pay off in the end.
post #27 of 37
Subtract a couple points from my score due to a 200mhz higher cpu clock (or maybe not since I ran less ram), but as you can see, when in extreme mode, 6850 pulls ahead. These are the two best scores for single card 5850 and 6850 when paired with same CPU (1090T). Obviously a 6870 will be even stronger.

That's a very nice graph! The 5850 has some muscle in CF. My 5850 has been a beast for me since I got it last week as a replacement from XFX.

If I was you and had the money I'd get the 6950 and unlock it to a 6970!

how is this at all relevant? its like trying to saying "what will make my car go faster? this turbo or the other turbo" then trying one in a school bus, and one the other in a pickup truck. the results you get won't mean a thing.

sorry for the rant.
post #30 of 37
my 6870's out benched a 900MHZ GTX 580.

2X 6870's = les then 500$

1x 580 = 499$.

WILL beat any SINGLE SOLUTION
