  1. Well, this is 7770 vs. 5850 single card configurations.


    If the scaling is similar, then 5850 by a longshot. If the 7770 has better scaling, still 5850, but by a shorter shot.
  2. The 6850 was about the same performance as the 5850, give and take.
    So using the 6850 as the baseline, here's a chart of resolutions in percentage.


    Then we add in Crossfire Scaling,


    The HD7XXX has far better crossfire scaling than the 5xxx series did.
    Plus the HD7XXX has updated eyefinity, less power consumption, cooler, etc.
  3. Definitely the 5850's. 5850 is a bit faster than 6850 and defintely faster than 7770.
  4. 7770 crossfire is a total waste of money

    might as well just get a 7850/7870 or 670
  5. gtx670 =)
    CF7770 is something for future upgrades, no something you buy from start!
  6. So...The 5850s are better than 6850s, then they are even better than 7770...I was also thinking to get only one GPU: 7850(and after some time make a CF with another one...if necessary):D.
  7. And there is something i don't understand...At that test, if you make a CF with the 6850, the performance is increased by 102%right(and at 7850 with 140%)?
  8. Maybe, but if you want to match and pass the performance of two 5850s you'll have to buy a really high-end card, like a 7950 or 7970/ GTX 670 or GTX 680.
  9. :O Think I'll stick to 2 6850s:D
  10. It's cheaper...could you recommend me a system? My max budget is ~1000$(I need a case, a processor, a GPU, RAM, Motheboard ):D.
  11. OK, I'm gonna need some time. You're going to use it mainly for gaming right?
  12. Here's what I was able to come up with:

    Core i5-2500k: http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072&Tpk=2500k
    Sapphire Radeon HD 6950: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102987
    Graphite 600T: http://www.corsair.com/pc-cases/graphite-series-pc-case/graphite-series-600t.html
    Seasonic 750W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151107
    8 gigs Kingston HyperX Blu 1600MHz: http://www.newegg.com/Product/Product.aspx?Item=N82E16820104262
    And slap all that on an ASUS P8Z77-V LX: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131824&Tpk=Asus%20P8Z77-V%20LX

    Total worth: $949.94. You still have about $50 for a DVD reader, but I'm not very good with those so I'll leave that to you.

    Now, the 2500k is a bit last-year, but it's still awesome. The 6950 is beastly(not as much as a 680 or 7970, of course) and you'll be able to put another one in down the road, if you feel the need. The mobo has full CrossFireX support, up to 4 cards. The PSU should be able to power 2 6950, I'm not sure, but if you go with more than 2 you'll need to upgrade it. The case has good airflow and "fantastic cooling from dual 200mm white LED fans". The memory is pretty self-explanatory: 8 gigs of DDR3 @1600MHz. What more do you need.

    I think this system will work great for you, especially for $1000.

    NOTE: The motherboard has a z77 chipset, so you won't be able to unlock the GPU into a 6970.
  13. Of course, I forgot something: http://www.newegg.com/Product/Product.aspx?Item=N82E16822148840

    It goes a bit over budget though. I hope it's not too much.
  14. I was thinking at an i5 3450 ivy bridge, and and Asus Radeon HD 7850:D
  15. The 3450 is a little less expensive than the 2500k, but you can't overclock the hell out of it. :D The 7850 is really close to the 6950 in both price and performance so it really doesn't matter.
  16. Isn't the case a little to expensive...?:O. Can you find a cheaper one, but big seize and simple but also stylish like that? Also a good airflow:D.
  17. NZXT 210 is cheap + nice :)

    That's going to be kind of hard to do. I need to know the exact brand and the quality of their products. I'm sure there's some no-name case that's just as good, but 1/3 of the price. I checked out akamrcrack's suggestion and it's pretty nice. Looks good too. You can go with that, if you want.
  19. That NZXT 210 Rocks:O+ Icould take the Elite Edition or the 220...The same price(almost)but...I'll also take the MSI 6970 Lighting Edition(but, first, is it better than Asus 6950?), Intel, etc...:)
  20. You can even afford a GTX 670 in this case. The total will be ~1040$ though. If you get the 6970 you will save $50. The 670 seems to be about 20% better than the 6970, so if you can get a factory overclocked 6970 you'll be better off with that.
  21. Yeah, I'll get the MSI Radeon 6970 Lightning. Maybe I'll Overclock it, but I don't think that will be necessary:).
  22. It probably won't. Most games don't require more than a 6850. Good luck! :)
