New Tech is coming out so fast these days that its a waste of money and resouces to keep out dated platforms up to date it seems.
Socket 1366 boards are getting hard to find these days and tbh 920's, 990x's are still plenty good CPU's to run. I had my old trusty Giga UD3 finnaly go out on me after 3 years or so which I was running a 990x @ 4.8ghz and used my Giga UD7 and 2500K @ 5.0ghz as a replacement until I get a 3960x system up and running, I feel like I took a huge step backwards. Don't get me worng tho the 2500K system does just fine but I have gotten used to more cores & memory.
Just watch as the people who end up getting ARM or ATOM laptops and tablets start using them, loading up there junk and start complaining about how slow they are. ARM & ATOMs suck and we all know it, but people buy them to save a few bucks then complain about performance.
As far as TRIM goes I don't think I have run a platform that has ever used it as I mostly run Raid 0's all the way back to my older MTRON Battleship which lasted 5 years, now replaced by two 120gb Intel 520's and I get better performance vs 8 of the MTRONs. Its not the end of the world to me at this time because it won't be that long until I upgrade to a platform that I can use TRIM on Raid's.
Why don't we see 8 core desktop CPU's ? Main reason is heat, and well Intel is stuck with the mindset that they know best. We all know that we can use a nice water cooling setup to cool those down but they have to design them to run with air coolers or they would get to many blown up CPU's in the RMA channel.
The server world is waking up also for some applications. I build high speed servers for a living and at first my clients don't believe that a server can run at 5.0ghz so they get a test unit. First thing they say is OMG !! then we get phone calls like... I just keep throwing stuff at it and it doesn't slow down. We have our HSSM - High Speed Server Modules installed at Equinox NY4, Chicago, LA and this month in the UK and every single client says they will trade stuff like IPMI over speed anyday as there are ways to work around it. Will we ever see unlocked Xeon E5-2687W's, I don't think so which is a shame as I would kill for those, so would my clients.
