6850 crossfire has about the same performance of a single gtx 580.....if it would be cheaper for you and you have the motherboard and psu to support the two cards you could go that route. I would recommend you go the single gpu route though. How much would you be paying for the 580? If its near $400 I would look into getting a gtx 670...it uses less power and is faster.
yeah i keep hearing that but I have a pretty low budget and i have a 850w psu and really i just want to be able to play all games on ultra for the next year then I think ill get a crossfire on the 670 and possibly a second generation on the bulldozer if they are out so do you think that the crossfire and 8120 will last me at least a year on all games?
are you saying you want to purchase a gtx 670 and eventually get a second 670? if so if your psu is a good quality unit you could do it provided your motherboard supports SLI as well....and as far as 670 SLI goes it will definitly last you a year on all the games maxed out. It is overkill for almost everything out there now....last question what resolution are you gaming on?
ahh so you are saying you would crossfire two 6850s now and then get a 670 in a year? two 6850s would give you great performance. just a little shy of the 670 so I would say yea it would last you a year
microstuttering is very possible but not guarenteed....it all really depends on if you notice it or not too....most people wont even notice it....if you can live with your one 6850 then I would def stick with that and just upgrade everything at once....you would have a much more satisfied feeling....thats why I am still rolling with 285 sli ....I am gonna build a whole new rig here soon so I have a major improvement
I have heard things about them but nothing too good...if its anything like the recent past its gonna fall way short of expectations. AMD has always been great performance for the price chips but never been top performers...only time will tell
