ok....and do you think that windows 2008 is better than windows 2008 r2 as workstation??......I ask because i want to install a new S.O.. My Laptop is a Core 2 duo at 2.2 Ghz, 4 gb of memory 320 gb hdd....
Windows 7 takes advantage of multi-threaded machines especially in encoding and productivity. If you don't have a 6 core AMD or a 8 thread i7 it is really not going to benefit you that much. The disadvantage of R2 is that you are forced to use 64-bit and it is a little more resource intensive than 32-bit server 2008. The great thing about 2008 is you still get to use all 4GB of your RAM and do all the daily tasks you would perform on R2. The memory footprint is quite noticeable. If you really enjoy the features of Windows 7 my personal recommendation would be to just run 7. I'm not trying to advocate that server 2008 is the greatest operating system ever or any propaganda like that - from my personal experience its just been the one that has run the best on my machine.
Here's a Passmark benchmark comparing 2008 64-bit to windows 7 64-bit on my machine:https://spreadsheets.google.com/pub?hl= ... utput=html
As you can see server 2008 performed quite better over 7 in 3D Graphics and Disk score for some reason.
I can't explain it technically, I just like it. Your best bet would be to try out R2 first for a little bit and then switch to server 2008 and feel the difference for yourself. Its the only way you are going to be for certain which one you like best. That is my advice my friend.
