<p>As i am thinking of builing a system with a evga 670 i was wondering how much better a similarly priced AMD card would be in mining?<br>
<a href="https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMD_.28ATI.29" rel="nofollow">The bitcoin wiki</a>
shows a hashrate of 406MH/s for the GV-R787OC-2GD  (a $250 card) while the EVGA GTX670FTW 2GB gets only 112 MH/s (a $400 card).</p>

<p>This seems really off to me. Is there really this big a difference?</p>

Is there really this big a difference between AMD and NVIDIA?

As on many websites it says AMD is so much better for mining while because NVIDIA has Cuda everyone says its best for editing why doesn't cuda drive up Mhash/s?

CUDA's a software framework for making GPU-based software eaiser to write. More stuff supports NVIDIA cards. Bitcoin GPU miners support both, so CUDA doesn't matter.
