Re: CCL:dual-core Opteron 275 performance

Thanks for the review.
 While the results are very impressive I wonder  what the results would
 have been if you compared 4 3.2 Xeon's against the two opterons.
 A quick look at pricewatch.com shows the Xeon 3.2 selling for USD $310
 were as the opteron 275's are going for USD $1328.
 Also I would be interested to know if the Xeon processors had 1 or 2 M
 of cache.  I have found this to make a difference on certain
 calculations.
 Anyhow thaks for posting the review.  I am looking into building a new
 test system and I will certainly be looking into AMD processors.
