Hi I currently have HIS Radeon HD 6850 coupled with E7300 @ 3.33GHz & 4GB DDR3 RAM. I am hoping to update my rig in 6-8 months.I know GCN is one of a kind but I am somewhat in love with my buddy HD 6850.So if I buy 7950 I have to throw away the 6850 at minimal price or I can buy another 6850 for CF keeping in mind the renowed almost 100% scaling on the 6850s.

So what should I do-Power isn't a factor for me

6850 will cost me 10200 Rs incl Tax & Sapphire 7950 3gb will cost me 26500+ rs incl Tax.

Plz give just unbiased & logical explanation
NOTE:-I'll change pSU and buy i5 2500k or i7 2600k possibly

both good options, one is cheap and one is better. really comes down to what you want. a 7950 will pretty much double the performance of 2x6850, it will also be a single card so no worries about whether or not a game uses crossfire, or how well.

the 7950 will cost you twice as much though. so it comes down to you

As per the above 2x 6850 will close in on 7950 in some and even surpass given the scaling won't it? Maybe I am being more inclined towards 6850 but that's because I will make a detailed scrutiny before I discard it.

May be these two arent exact comparison but rigs are pretty same and gives a rough estimate-HD 6850 CF ~~ HD 7950 stock given same CPU RAM

Further to these one thing I have noticed-A staged decrease in driver optimization and performance for 6 series from Catalyst 12.1 onwards and added to it is the 12.11 driver that gives whooping 10fps avg increase in BF3 for &SERIES ONLY .Ironical how much AMD and Nvidia will go to ditch prev gen performing crds to sale Kepler and GCN

You didn't put the resolution you will be playing at. I suggest oc 7870 for 1080 res, or oc 7950 for 2560 x 1600 resolution. If you can spend, get the GTX 670, it's way faster than the OC 7950
1) I bought the Gigabyte 7870 on 10/20 for $249 plus $20 rebate. So price wise, it's better than the 7950.
2) You can oc the 7870 to be running as fast as the 7950. So performance wise, it's same

The nice thing about the 7950 is that it uses less power wattage wise then the older 6850. Something else to consider.

If 7950 gives even 10 fps more for an extra price 6000 Rs then would it be viable since extra 1fps is costing like 1000Rs each~ 11 to 12 $ !!!
6850 CF~20k Rs
7950 26k
Diff-6000 Rs~110 US $
per xtra fps=110/10(assuming 10 fps more)=11 $ per FPS???? !!!

I game at 1600 x 900 -My sweet 16:9

Single cards are generally better overall. Not everything works well with Crossfire.

The GTX 670 is not faster, especially with the new Catalyst 12.11 drivers.

------

If you can get a Sapphire Vapor-X 7950, I've heard massive OC numbers with that card (something along the lines of 1200MHz core), enough to surpass a non-OC 7970 GHz Edition.

If you are playing on 1920x1080 or possibly 1920x1200 then a 7870 might work just fine and ease up on your budget, but if you can afford it, definitely go for the 7950.

Another thing to consider is power consumption and the heat thrown off from the cards you'll have to deal with in your chassis, and also that CrossFire doesn't play well with every game. Considering those, a single GPU is definitely the way to go.

Ha Ha :lol:  --GTX 670 with catalyst 12.11 ...Did I see right? You spoke of Nvidia with AMD driver? :pt1cable:

Well I have two Radeon HD 6850s from XFX. I used to run them in CrossfireX and they were the first Graphics setup I ran, in my LAN rig, in order to play Battlefield 3.

Even-though my Frames per second were above 40FPS I would intermittently and randomly get small lock ups when playing Battlefield 3 at 1920x1200 with Ultra settings.

The problem? I was spilling over the 1GB framebuffer found on the Radeon HD 6850s and ending up utilizing and swapping textures back and forth from my system memory (which would cause a sort of jerkiness in my gaming experience).

You see Graphics RAM does not scale. Two 1GB cards equal 1GB in terms of Frame buffer. That is mostly due to the fact that both cards, when running crossfire, have to load up all of the textures to be displayed on the screen even if they won't be personally/individually displaying them.

IMO 1GB is usually not enough for a comfortable 1080p gaming experience if you plan on playing the latest titles.

its enough as long as you are not the type to max out every game.
funny how people say comfortable gaming experience only comes when they are able to max out every game and maintain 60+fps.
most people dont need that.
so yeah 1gb is enough for now if you are ok with not maxing out every game
but in future it wont be enough like in 2 years
