Quote from WinstonTJ:
I'm not going to lie - there is a big difference between DDR2 and DDR3 just as there is a big difference between 45nm and 32nm architecture - but when I say big I think it's misleading because so many tasks are mundane and trivial on a computer. What is the difference between "super fast" and "lightning fast"??
Most of the HFT servers I host are actually Intel Atom CPU's because all they need is a dual core and 4-6GB of RAM. Most people get a hard on for RAM and CPU cores - most people use less than 25% of their machine's capacity.
I've never owned an i5 so I can't speak to them. The nice thing about the Dell & HP workstations is that Xeon processors work in pairs - which allows you to take a single older CPU and double it - right down to L2 and L3 cache. I go through so many Xeon x5060 CPU's that there is a pair at the top of my keyboard right now. *** sorry these are x5080 - 3.73ghz... but 4mb of cache is small... how about when you combine two and now you have 8mb of cache, 4 logical and 4 hyperthreads - for less than $50.... for the money you simply can't beat it.
And the issue of the motherboard....
Most computer buyers think the CPU is the brains and end-all of the computer.. .nothing matters as much.
I disagree. IF the CPU is the "brians", then the motherboard is the "central nervous system".
If one is looking to get a workhorse on a limited budget, better to go with an older workstation for its server-class components. It's like having to spend $10,000 on a car... would you rather buy a new Dodge Neon or a 2-year old Lexus with 5000 miles on it.
Before I replaced all my computers 3-4 years ago, I was running Dell Dimension 8300s. One I sold to a friend who still uses it daily.. that's going on 11 years.. and the Dimension 8300 was a mid-level rig, not even a workstation class machine. (I'd also sold him an el-cheapo Compaq... needless to say, it's not still running.)
