Crossfire 6770 or a single card within the budget price range?

post #1 of 32
Thread Starter 
I know this topic is repetitive but I just want to clarify some things...

But first, here's my current rig:

Athlon X3 3.0ghz
Asus M4n68t Le V2
6GB ram
Sapphire 6770 vapor x

My planned rig:

i5 2500k (yes, I'm ditching the ivy bridges [OR, persuade me to get to ivy bridge])
Asrock Z68 extreme 3 gen 3
upgrade to 8gbram

Now here's my problem...

if ever I chose to crossfire 6770, would the regular sapphire 6770 (without vapor x) still be compatible with vapor x 6770?
or is it still good to invest in a single card rather than dual 6770?

I'll use it mainly for:

-3DS MAX
-heavy gaming bf3, mw3, crysis (still havent beaten that yet due to crappy specs of my pc before), and other modern games out there
- audio, video encoding
- videoediting (sony vegas)
and finally, Adobe after effects.


Thanks guys! please help, I don't know much about dual gpu set-ups so please help me XD

Get the Sapphire 7970 o.c. single card, great cooling.
I would always get the single best card first then crossfire/sli after when its absolutely needed. Why go through the trouble of a multiple card system and tweak and tune drivers on multiple cards for some games to run good when all games will almost always run great on a single card.

If you chose to crossfire, then a regular Sapphire 6770 (or any other manufacturer) would absolutely be compatible with your current vapor x model. I have been running crossfire 4850's on my rig for a few years now and can still play new games with most settings maxed (no/low AA/AF) however there can occasionally be driver issues running 2 cards (i.e Skyrim at launch) so there are pros and cons. I'm personally very satisfied with using crossfire and would recommend it to others, though I know there are others who feel the exact opposite. Hope this helps.

To give you an idea my 5770 crossfire setup ran BF3 on High with 2xAA no problem. They sipped power too. Only like 300watts total system load max. It will be the cheaper option for sure. 6770's can be had for around 100.

With your cpu and only 2gigs of ram youll run out of ram/processing power far before you can reap the benefits in a game like bf3. Need more ram and to oc that cpu a ways as well. But a 6770 crossfire setup will run most anything you want with medium/high detail (no aa or af) at very playable frames.

I don't plan to add AA on games tongue.gif maybe 2x will be sufficient. Also, I have a 1366x768 resolution atm. If i have a 22 inch 1080p, could the crossfire be sufficient enough to play crysis at that level? (with the 2500k)

it's always best to buy a single card that you can afford right now than buying 2 cheaper cards.

After all the headaches with 5850 crossfire, I cannot recommend crossfire to anyone anymore. Support is sporadic and performance is really inconsistent. To answer your question though, you should always crossfire with an identical card in the same class, e.g, 6770 1GB with any other 6770 1GB. If clock speeds are varied, crossfire will pick the lower of the two clocks to set across the cards. You can go back and manually raise the OC yourself and find a happy stable clock later though.

If I were you I would just go with a faster single GPU as many others in this thread have suggested. AFAIK multi-gpu setups in general aren't supported in rendering apps, so added incentive to go the single GPU route. Personally, I don't think any card below 68XX series or 460/560 is worth running in multi GPU.

Thanks for the replies.. So the 6770 crossfire setup is a NO-GO (i guess)...

So what'll be a good and budget-priced cards to take on crysis on 1080p?

Crossfired 6770 is beat out by a single 6870. So, what is your budget?
