    2X6800 vs 7800

    I'm about to buy a new mobo and Athlon64 2Ghz.with the 6800 card, 256MRam on board. To run 2X6800 (*which buy the way would be better then 1X7800) you need to have SLI mobo with PCI express.

    I'm buying 1 card for now and then when budget allows, get the 2nd card. Of course 2X7800GT or GTX would be kick ***. This site did an excellant review of the 7800GT vs GTX and showed other cards as well.

    What cards are you comparing? 6800, 6800gt, 6800Ultra sli vs 7800gt or gtx?
    It'd cost more to get two cards, but perform slightly better.

    Just get one 7800GTX and then down the road when you have more money pick another one up.

    As long as they are PCIe, SLI compatiable, you buy the same brand card, and you have an SLI mobo, you can SLI them.

    WRONG. 2 6800's are still better than one 7800GTX, but the 7800GTX performs outstandingly, there would be no need to pay extra money for 2 cards when you can get nearly the same power out of one card. Simply, 7800GTX will do anything you want it to for less money than 2x6800's

    Get the single 7800. It will perform on par with the 2 6800GT's and then, when prices go down and you have more cash, you can get a second and see a big boost in performance when you need it and can afford it..

    i heard and read somewhere that a 7800gtx beat 2 6800ultras in sli mode

    I thought it was, maybe at one time it was, but since SLI has advanced quite a bit, they might have worked around it. I found this and it doesn't say you need the same card, but I'll keep looking.

    EDIT: But:

    That contradicts it. (Full link here)

    7800GTX vs 6800Ultra

    I was checking prices for Ontario GTA area.
    What I found was:
    1) Extreme PC :
    MSI GeForce 7800GTX at $675.00
    or MSI GeForce 6800 Ultr 256MB at $647.87

    2) TigerDirect.ca
    Highest Price BFG or XFX GeF 7800GTX OC at $735.99
    Lowest Price, LeadTek GeF 7800GTX at $689
    and BFG 6800 Ultra at $607.99

    Interesting package at TigerDirect???????
    What about Dual package of XFX GeF 6600GT 128MB at $499.99
    The problem here is you have instant SLI mode but no where to evolve to!

    Soon to be owner of K8N Neo4 Platinum 939, Athlon64 3500, IGB DDR PC3200 and whatever DARN Video card (s) I can figure to buy.

    I have one 6800GT and it rips through any game I have thrown at it so far. Why would anyone get two 7800s? Just so you can say "I have 7800SLI"?

    Get one for now, and the the second when (and if) you find the single 7800 isn't handing your games anymore.

    That's my two yen.

    2 Japanese yen = 0.01819836 U.S. dollars. Therefore you need ~2.20766 yen to make .02 USD which would validate your statement which should have said, "my 2 cents" or some combination of the phrase.

    My 2.20766 yen :grinthumb

    Oh, but you are wrong there. American children love to have foreign coins, so I constantly bring over Japanese yen in exhange for 2 cents per coin.

    In essence this means my opinions although worded as being worth 2 yen actually are worth 4 cents. Double that of normal people's 2 cent opinions.
