Edit, in my previous post (deleted) I missed a higher-end dell model:
The highest-end Dell is the Precision T7500, right now on their website to make it match the BOXX (which it really can't, but let's pretend) the cost is about $5,200 (they have some sort of discount but I'm not sure of the details) -- this is the equivalent (kinda) of the BOXX 8550 XTREME series which goes for $8,317.00 with similar specs except with
double the processors and liquid cooling thrown in. The extra processor goes for $1700 on newegg -- and I'm sure the motherboard to seat two of them costs more too(not to mention the liquid cooling solution for 2 processors). Even
if you could get a Dell with double (the current top of the Dell line) processing power and liquid cooling (not likely) I still would hesitate to say the quality of build would be comparable to BOXX.
Pro gear costs $$$ no matter where you get it from... if you can afford it, why not go with the better option -- for alot of businesses this is just a tax write-off anyway.
I need to make some cash so I can get me 2 of those beasts -- it would make rendering a joy
Best,
Jason.
