I Don't game, I do a lot of video encoding/audio stuff and will set up Plex media server on the system. I've got two questions, anyone use the TZ77B ? I'm a bit confused on Biostar's boards, they have a TZ77A, TZ77B (can't see any difference) and a TZ77XE4... I assume if I'm not gaming (no need for SLI) then the TZ77B should be plenty? other question, I'm going to use my WD 1.5TB as my OS drive, is Windows 7 gonna run dog crap slow? it's SATA 150...I've been out of the loop for quite a while, do I need to get my flame suit out of the closet?
