Hexa. More cores is better for VMs, they need massive threading. The more cores/threads, the better is load handled, fine tuning also works better.

@serverian I second @Maounique's recommendation. The Xeon L5638 is also a year newer than the Xeon W5590. GHz isn't everything, and on a multi-user system where you want to deploy virtualization the number of physical cores is more important than their speed, especially on large servers.
What about for database and web?
@serverian Can you post the complete server config for the hexa core and what you intend to do with it? Also, are these dual socket or single socket servers?
@marcm, there is no server, just taking opinions about the processor config. Dual socket.
Then I'll stick to my original recommendation: get the hexa core L5638 - you can do better with it regardless of the task, especially when it comes to virtualization.
Dual hexacore? I'm getting arouse
L5638 vs W5590 http://ark.intel.com/compare/41643,48766
Clock for clock, westmere is only 25-50% faster than nehalem so L5638 ain't much faster given it's low default clock speeds. For performance to price ratio, better alternative would be dual Xeon X5650 to X5670 http://ark.intel.com/compare/47922,52581,47920,47921,41643,48766
Or Xeon E5649 http://ark.intel.com/compare/52581,47920,47921,41643,48766
@eva2000 we have dual hexa core E5 servers and they perform really well, so if the OP could get a dual Xeon E5 2620 2.0GHz /w 15MB cache per CPU they he should go for it. Your recommendations are also very solid :-)
Sandy Bridge to Westmere is a lot different than Westmere to Nehalem. Westmere to nehalem was just a die shrink.
Indeed if Intel E5 Sandy Bridge-EP cpus are an option even better as they have ntel Integrated IO and Data Direct IO tech which folks seem to overlook

At home i'm running dual Xeon E5-2650 octa-cores = 16 cpu cores/32 cpu threads
Nice! Now I'm jealous :-)
Me too. I don't have that @ home. I wouldn't know what to use it for though.
for me one use is for web/db server scalability testing i.e. revisiting my old tests again http://vbtechsupport.com/606/
just on the edge though as mysql 5.6 now scales to 48 cpu core/threads > 16/32 cpu core/threads heh
Moarrrr cores!
