  1. Btw 4870x2 is on sale. I didn't see any review comparing 4870x2 against 2 4870 in crossfire. For sure 4870x2 has 1gb (yeye 2gb but 1gb for each gpu) while 2 4870 has 512 mb (yeye 1gb total but 512 each gpu). You will have your answer in 1 week maybe ;)
  2. LOL, two HD 4870 in Crossfire are enormous GPU power. No worries, you'll get good performance.

    Add more RAM, that's probably the weakest point in your setup. The GPUs are just fine.

    Is it a maximus formula x38, or a maximus II formula P45? If it's the P45, then sell it and get a P5E Deluxe X48, or sell the HD 4870 cards and get an HD 4870X2. You will get a bottleneck with P45 and two HD 4870 cards.
  3. its the maximus formula i believe my computer guy said hes sold alot of them with 2 4870 crossfired with no problems so i took his word for it i dont know my computer was always built for video editing i just recently got out of that and started to upgrade my computer for some serious gaming.
  4. yeah... ebay those suckers and get the 4870x2 if you dn't have an x48 Mobo.
  5. well i havent recieved my motherboard yet i can always change my order whats the difference in the x38 chipset and the x48
  6. If it's the X38, it's fine, it will run both cards at x16+x16, i.e. full speed.

    If it's the P45, it will drop to x8+x8. That will reduce performance by more or less depending on game and resolution. (It hurts more at higher resolutions, in general.)
  7. ok i just checked my receipt it says asus P5E i got is that ok?
  8. That's an X38. You'll be just fine :)

    What kind of power supply do you have?
  9. i just bought a coolermaster power duo 650w he said it should be more then enough to run 2 4870s on crossfire since they dont require as much amps or something like that he said it should be fine.
  10. OK, it should do. Not my favorite brand, and not much room for disks and sound cards and tuners etc etc, but it's OK.
  11. so i shouldnt worry about my board it will run my crossfire fine? thats what im really worried about now.
  12. X38 is fine but the ATI tech I spoke with today said there is a known problem with them with crossfire. I don't have one so we didn't go into details. Most likely correctable with chipset drivers or bios update.

    A P35 or P45 would take a 10-20% in crossfire.

    If you do go for one never buy a OEM ATI card the warranty is crap.
  13. ok ill stick with the x38 chipset then seeing its like 100 dollars cheaper too so thx for the feedback guys.
  14. P45 has pcie gen2, 8x is the same as pcie gen1 16x.
  15. would there be a tremendous loss from keeping my 2 4870s crossfired instead of buying a 4870x2
  16. no, not at all. What is the max resolution you're playing? The 4870x2 vs 4870 cf wont make any noticable difference unless you're playing on 2500x1600 maxed out...
  17. ok sweet i only play at 1680x1050 so i just bought the second 4870 today and i dont want to find out i dished 600 dollars for something that isnt gonna last atleast the year and i bought 2 of them for better performance but as long as its not a big noticable difference ill stick with my brand new sapphire 4870s
  18. I have a GA-X48-DS4 with one HD4870 so far... I'm planing on getting another one in maybe a year, I guess that will be the time when I could see any real difference when playing 1680x1050 with two 4870 instead of one. Let us know if you see any difference in FPS in games (I suppose 3D Mark score will improve, but that is not really saying anyhting...)
  19. will do thx ill stick with my 4870s for awhile i think 2 of those are more then capable of running future games for awhile i believe plus i cant really return them now so gotta be happy with what i got thx for the feedback guys im gonna benchmark the 2 4870s tommorow.
