core clock vs mem clock vs mem interface vs mem bandwidth

i have a question similar to fox9's

he asks for a comparison between the evga 7600gt and the evga 6800gs. i'm trying to compare the evga 7600gt and the xfx 6800gs, however. the difference i see between the two is the core clock, memory clock, and memory interface, mem bandwidth:

7600 gt: core clock 580MHz mem clock 1500MHz mem interface 128-bit mem band width 24.0 GB/s

6800 gs: core clock 485MHz mem clock 1.1GHz mem interface 256-bit mem band width 32 GB/sec.

both have 12 pipelines. is there anything else i should consider between these two.

**edit:so which is better?or which specs should be considered aside from mem interface and RAM**

im trying to build (my first build) a computer that is windows 64-bit and sli-compatible with a athlon 64 X2 3800 cpu so i wanna lean to the 7600 gt if possible. i was told by a freind to stick with the higher mem interface, which is not windows 64-bit compatible. i'm sticking with nvidia on this one btw

any help or possibly other suggestions in that price range is greatly apprecitated, thanx. although very informative, the above mentioned thread left soem questions becuase it doesnt answer my question about memory clock nor mem bandwidth.

  1. What is your question?

    As far as the 7600 GT vs the 6800 GS, the 7600 GT is the better card, regardless of memory interface. What the numbers don't show you is the 7600 GT's better architecture/

    both aren't that good a choice for SLI, because a single 7900 GT (or X1800 XT) is cheaper and will perform better than two 7600 GTs.
  2. well u helped, i hadnt considered architecture, good point
