Should I buy two 4890's in Xfire?

I'm building this rig:
AMD Phenom II X4 955 BE
MSI GD70 790 FX Motherboard
4 GB OCZ Gold 1600 Amd Edition
MSI Cyclone R4890 OC Edtion X 2 in Crossfire X
Coolermaster HAF 932 Case
Corsair 850 TX (850W)
Samsung T240 HDTV Monitor

I saw many reviews on 4890 and 4890 in crossfire. They all show that a 4890 performs better than a gtx 295 in Crossfire X. But I understand the deal with 'fps' like what is the fps that means the game will run smoothly without stumbling on any parts. A single 4890 can run all games at 35-50 fps in HD (1920 x 1080) but does dat mean the game is running without stumbling on any parts? The only games dat I saw dat the 4890 perform bad in are stormrise and crysis warhead, they show that it runs on 20-30 fps on full HD. Does dat mean its running smoothly? Is it worth buying two 4890's? because all I want is that games run really smooth without any glitches or problems of any kind. Or should I wait for the 5870 due in November? The more money I save buying this rig the better. So wat minimum fps means the game runs smoothly and what should I get?

  1. dont do this. Really dont. Better take 5870 when it's out. I think you can wait 10days to have the same performance for the same price but with one card + dx11 +lower power consuption + future possibility to add another one.
  2. I'd wait, at least until ATI releases the 5XXX series, or if you have the patience, until Nvidia releases its own DX11 parts, although that is still some time off (I hear maybe early December).
    An alternative to the long wait is to do the build and install a 'placeholder' card
    Either the HD4870 or GTX260 will play most games at high at that res without too many hiccups.

    not bad option either :)
  4. thanx guys but I still don't know what minimum fps means smooth without hiccups. and I saw another chart which shows that a single 5870 is 20% faster than a gtx 295!! if its true I'm definitely waiting for the 5870. But what will its retail price be? (hope its around $300-350)
  5. The launch price will be high, rest assured but right now all we have is rumour and speculation both of which put the 5870 somewhere near the GTX295 in price.
    The minimum for a shooter would, in my opinion, be 30 FPS, any lower and the game starts to feel sluggish and unresponsive. For fast racing games at least 45FPS is needed, again to prevent the game from feeling slow. More pedestrian games like turn-based strategy titles can drop to 10 FPS and still be perfectly playable.
    Take a look at X-bitlabs and Hardwarecanucks, both as I recall give max, min and average framerates in their reviews.

    but here it says that 5870 X2 will be priced $599 and 5870 will be $350-400 and whats "XBox 3"?
  7. I woz wondering should I go with the i7? Im neither an amd nor an intel fan-boy type so i just want good gaming performance...So instead of ma current config how much better or worse would this one be?:
    core i7 920
    asus rampage II extreme\asus p6t deluxe v2
    6 GB DDR3 1600
    ATI Radeon 5870
    Samsung T240HD
    Kingwin 700W
    Coolermaster HAF 932
    I knw this would be a lot more expensive than the amd rig but is everything okay?
  8. Switch to a better PSU, the rest seems more than OK to me.
    Just a point, the i7 tends to run hot and seems to like being overclocked, I'd suggest you add a better cooler and do some research on overclocking to get the best out of this beast you're planning;)
    This is a very good PSU, not too expensive either, given its quality:

    Otherwise look for Corsair, OCZ, Antec, Silverstone, Pc Power and Cooling or FSP, 650Watts will be plenty for a single card, but up it to 750-800 if you plan on Crossfiring:)
  9. @coozie 7: I knw this aint related to the topic but do u knw if the new Xbox 360 with the jasper chip has RROD's? If they don't Im gonna get it... Coz that way I can play games on ma t240HD :D rite?
  10. Sorry, no idea, mate, unless someone else knows, all I can suggest is a Google session.

    And I really mean it about the PSU, of all the components you should not skimp on, it is the one.
  11. ohk will do :D thanx for all the help
  12. A another choice than the would be to crossfire 1gb 4870s. this is still one of the fastest setups out there. Alternately, like he said, you could just wait for the 5800 series but then the 4870s will drop in price, so you will likely still get more bang for your buck with crossfired 4870 than a 5800 card.
  13. but the HD5000 series have dx 11 over HD4000 series ;)

    But what games need dx11 rite now? And wouldn't two 4890s in CF be a lot better than two 4870s in CF? Or would the performance gain be too minimal?
  15. If money isn't that too big of an issue, Trojan, get a 5870x2 (mid-october, I hear), and if you're still not satisfied (IE: you're insane), do CrossfireX with 2 5870x2's.
  16. Most consider 30+ fps acceptable and 60+ fps to be ideal.
    I'd definitely go for an i7 build if you can afford it and wait for an HD58xx card. Either of them should give extremely good performance at 1920 x 1080.

    yes you're right about that. but he doesn't need to look for more upgrade later if he want to play games with dx 11 features. but if he really don't care about dx 11 then 4890 in crossfire will be good for him
  18. so 1 5870 would last me...........how many years of gaming?
  19. not sure about that.....maybe until dx12 is out.... :D
  20. Actually im building a sub $2000 gaming rig. with dual 24 inch monitor and razer mouse/keyboard/mousepad/headset.
    Total would be around $3k.

    anyways, only thing on the list to add is the new ATI 5870.
    I've been waiting for over two weeks now...
    now I only wish that the time goes faster. =/
  21. I know u've posted this many months ago but now on 2010 if u want a real DX11 Gaming Experience, I suggest U higher than that, If u use a TV as ur monitor so u have 1920x1080p screen, I Suggest u a nVIDEA 480GX, or if u use a 21inches LCD/LED i suggest U a 5890, which works better on higher resolutions....
