Welcome to Namepros, CMSports.
Yii.com is brandable to the extreme. Forget the 'y' being a not-prime letter, Yii is a killer word, short for Yikes, playful for comedy shows/movies, scary for horror/suspense, well-known, and there are many, many companies who would love this as a name to represent their online presence.
I've seen much more mediocre LLL go for between 5,xxx - 15,xxx. Don't be hasty with your name. Almost any reseller who could afford it would give you 5K for it in a heartbeat - and I would

. But you absolutely should not sell for less than 15K as a base minimum, and only if you're in a hurry to buy that expensive medication to get your infections cleared up
Best to ask for a lot of advice on how to efficiently reach bidders for this one. Don't be in a hurry. A few more weeks or months of work, will increase greatly the price you'll get for this one. Your ace-in-the-hole is this: you know that if a FEW people have been searching you out and making bids or asking about prices on your name, then a LOT of people will be interested if you just find a way to let them know about it.
Excellent name, you'll do well with it. Won't make you wealthy (unless you do some killer development), but will buy you the new car.
DragPix or DragPics would have had some small value, but dragPixs has zero, IMO. Even developed, too easy to make many typos of it.
Make some killer kash off Yii, then use some of that to invest in safer, defensible names that already exist, even better if they have existing traffic too.
And hang out more at Namepros; you'll learn a lot more about the game and will make less and less mistakes.
Care,
