  1. yeah you will absolutely fine, I ran crossfire 6870s with no problem with my rig and psu below in my signature,VVVV all I can say is beware of minimum fps
  2. You will need to oc your 955 to around 3.8 to get rid of any bottlenecking that may occur, what are your full system specs, monitors resolution and budget?
  3. CPU: AMD Phenom II X4 955 Gonna OC to 3.8Ghz
    MB:GIGABYTE GA-990XA-UD3
    GPU:Sapphire Radeon HD 6850 1GB
    HDD:Seagate Barracuda 1TB SATA3
    RAM:4GB Kingston 1333mhz
    PSU: CORSAIR TX650w
    Case: Cooler Master 430 Black Edition
    Sony DVD/RW
    Monitor Samsung LED 22''
    Resoution probably 1920×1080

    I was asking for crossfire for the furure when my GPU will get slow for newest games.
  4. looks good, go for it, just be prepared (and I speak from personal experience) for crap drivers and low minimum fps, from my use I always prefer a strong single card, personally I'd sell the 6850 and buy a 6970 or gtx 570, or wait for the next series of cards to come out by the end of the year or sooner
  5. So you are saying the 6850 is not that good at games or just for crossfire? The 6970 or 570 is too expensive for me :(
  6. no its fine as a single card but personally I would avoid mid-range crossfire, do some research there are serious minimum fps issues when considering 6850 crossfire.. If you can afford two 6850s you will be shelling out 350+ so how can you not afford a top end card, anyways I'd go for a high end single gpu, my 2 cents although if you choose to crossfire your 6850 then your rig will be fully equipped to do so.
  7. Oh okay thanks :) If I need to upgrade than a better way is to get a single high end card than to crossfire the 6850.
  8. yeah that is what im saying, but a single 6850 should be pretty good by itself, if you are not getting the performance you want and dont have the money to upgrade then the other options are start scaling back settings to get more frames per second, you can monitor fps while playing with a program such as FRAPS, give it a try
  9. I have a 6850 and would like to get a second for crossfire later. is everyone having this low fps thing or just some people? Does it happen with all crossfire setups? Is there a known solution?
  10. well its the nature of mid range crossfire imo, take a card whose minimum fps is not that high to begin with then add another card and you are getting less minimum fps then you were with a single card, this was my experience with crossfire 6870s, maybe im just more anal then most
