they say it's optimalized for workstation gpus, but in compatibility list it supports gaming gpus as well, so i'm asking, is it ok for gaming or is there any performance drop or something?
It use the C232 (server/workstation equivalent to B150) so its mainly use in the gaming segment to put an Xeon-E3 1230 or higher (4cores /8 threads) as a cheaper i7 no integrated graphic equivalent. You could probably find B150 equivalent to that board for cheaper if you aren't going to pick a Xeon-E3 CPU.
