I get very fast downloads from CF card to PC using either a USB3 Sandisk card reader or a blindingly fast internal SATA card reader. Obviously fast cards will help.
I wouldn't be storing on an SSD... far too expensive and unnecessary. On my two current home-built PC's I have the OS (Win7) and programs on a modest sized 180Gb Intel SSD, and local storage on a 2Tb HDD, then archive network storage on a five-HDD Synology NAS. BTW, I wouldn't go with Win 8. It's a dog in the tradition of Vista and the dreaded ME. Win 7 is the new XP.
If you were really needing maximum speed, you could keep a small folder on your SSD named "Current Project" and import your current job, do your work and then shunt it out again once you've done your post-pro. Photoshop scratch would also be on the SSD.
Here's a good tip, buy your RAM from http://www.crucial.com/
If you give them the specs of your EXACT mobo, they identify & send you the most compatible memory possible for that board.
