    I know it matters, but how much does it matter in the Gpu, I mean what differnce would I see in my gaming for say Dual Ati 4870's (1024mb total) versus dual Nvidia 9800GTX (2048mb total)....

    Another question I have is what is the purpose of stream processors, Ati always seems to have an incredible amount compared to Nvidia

    The only difference you'll notice with similar high end configurations are particular advantages Ati and Nvidia have over one another, like AA or "made for nvidia" games. Example: Unreal engine always performs better on Nvida. Example 2: Source engine performed better with Ati (at least in 2004). Example 3: Ati takes less of a hit when applying AA in crysis.

    Apprantly 5 stream processors for Ati equal 1 shader core for Nvidia, so 640 stream proc. = 128 unified shaders.

    Cool much thanks man, Although I thought ATI had shaders in addition to the stream processors, or is that just ATI's name for shaders?

    Stream processors is just another name for shaders but I believe stream processor is the name more attributed to ATi cards as every 5 shaders is actually part of a total 5-dimension processor. For example the a Radeon 3850 has 64 5 dimension shaders totally out to 320 stream processors. They all do the same thing, they are just grouped into fives.

    At present it seems the top-end ATi offerings do much better at very high gaming resolutions and high-levels of AA during benchmark tests. Everything else mentioned so far holds true so a top-end product from either company will deliver performance considering the price you're paying.
