I have a Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz in that ThinkPad T520 
and its really just fast enough for me. Easily. And thats just dual core 
and the mobile variant.

But yes, I´d go for Ivybridge now as well. In my case I will wait for 
Haswell cause that Sandybridge is fast enough. Even for most gaming I do. 
(Well with Planeshift Ivybridge would be good:)

I think at least with computing power to power comsumption ratio I think 
Intel Sandybridge and Ivybridge are *really* good.

I am not uptodate regarding AMD offerings, but I wouldn´t go for less than 
this regarding this ratio especially for a desktop machine.

If 8 GB then at least with the option to upgrade to 16 or 32 GB.

I do have 8 GB in this ThinkPad and while that is more than enough for 
usual case of me running on or two KDE sessions I have seen this box 
swapping to SSD in some cases. Like me having two VMs running concurrently 
to these two KDE sessions.

SSD might still be good bet. They are like switching from floppy disk to 
harddisk for me.

But then I have a 12 GB workstation with Ext4 RAID 1 on two Western 
Digital 1,5 TB drives and /home on NetApp provided 1GBit-NFS and yes its 
fast too. I attribute that to the 12 GB of RAM in the machine. It just 
caches everything :).
