Dell PE2970 with AMD Opteron 6core 2431 2.4GHz + 64GB 667Mhz RAM - 2435 is not available with Dell now
Dell R905 with AMD Opteron 8435 2.6 GHz + 64GB 800Mhz RAM - but this CPU is 4-8 way, I have chosen only 2P config
Both are very close on price and I am leaning towards the R905, please advise.
The R805 is a dual socket AMD Server that supports the 24xx series six core CPU's and is more of a direct replacement than the R905.
Other than that the R905 is a newer generation of Dell Server and I would tend to go with that rather than the older 2970 in any case.
