    While I think 2x1GB XTXs would perform very well, it's not good news for most users since almost everyone uses 32 bit windows. With 2x1GB cards, you're automatically limited to 2Gb maximum memory, but realistically closer to ~1.7Gb once all other devices have been taken into account. This really isn't enough for Vista and most modern games, which the XTX is ironically aimed at.

    2gb is enough for most games, however having the same amount of gpu memory as you do actual system ram just seems stupid.

    Remember that it still only 1GB of VRAM, the two gpus need the exact same data in their RAM, they don't work together, they produce teir results independantly.

    I don't want that kind of heat and wattage going on in my system.

    That may be true in any real sense but I was under the impression the memory from all components was taken off the 4GB limit in 32-bit windows regardless of whether it's actually utilized or not? In which case, the realistic maximum under 32bit windows would be around 1.7GB.

    GDDR4 version is still listed as HD2900XT, just that its 1GB. As designs go the HD2900XT is hardly bandwidth limited afterall.

    to elegy:

    a 32 bit cpu doesn't limit the amount of graphics memory you can have. the cpu only addresses the system memory directly. the gpu has its own processor(s) that works with the graphics memory (graphical processing unit)

    even with 2 Gigs of video memory, you can still have 3.x gigs of system memory in 32 bit windows.

    wikipedia thinks differently. i assume this is the 1024 meg vs 1 gig problem continued out to exabytes.

    No.
    18e18 that's in bytes
    2^64 / 2^60(1 exabyte = 2^60 = 1,152,921,504,606,846,976 bytes) = 2^4 = 16 EB. So, you were right. And I've posted the number of bytes
