7770 Crossfire???

post #1 of 5
Thread Starter 
Soo I was just thinking. Building my friend a computer soon and was going to get a 7770 for him.. ANd I realize 7770s brand new are only 120$ or so.. When my 7850 was 250$ but now is ~200$. And I only want the xfx 2gb one. According to Toms a 7850 in general performs ~20% better than a 7700 but it also costs 2x as much... Isn't this a bit ridiculous? Why are they that cheap? Why would I get another 7850 for 180$ for crossfire when I could sell my 7850, that money alone will be almost enough for 2 7770s without much performance loss. Is it just me or is that one amazing value for the money? Now to check if they only come in 1gb...

Nope, the 7850 is better:

Multiple cards has a whole host of problems. I'd ALWAYS take a single nice card over multiple smaller ones. Not until I need more than the nicest single card would I want more than 1 card.

Well I obviously know the 7850 is better but it said general performance only 20% better. But I think they 7770s are super cheap compared to 7850s because none come in 2gb editions.

And I thought most of those issues were taken care of. More logical to do one card I agree but just the fact that I get to live my dream of having 2 cards, and I can shut off a card through CCC I was told. I'd only use the 2nd one for shiz like crisis 3 basically. Maybe if I get metro or something new comes out.

7850 is much better (up to 50% in certain cases) than 7770 . http://www.anandtech.com/bench/Product/777?vs=778

2x 7770 performs a little bit better than 1x 7850 - but not always as well.

What does your friend play. Note that crossfire works only full screen so some games that dont use true fullscreen (but instead use border-less window which looks similar to fullscreen) do not get any benefits from crossfire - second card would be sitting there just idle.

I would go with single stronger card with 2 GB of vRAM if budget allows.
