Obviously it depends on one's goals but I wouldn't put off training BJJ due to strength levels; few martial arts are really about "gym" strength, especially as a beginner.
I'm pretty confident that it takes a whole load longer to become proficient at any martial art but particularly BJJ than it does to gain decent strength levels.
One of the overlooked benefits of martial arts that compliments strength training is flexibility; I've lost count of the number of built guys who have come to train with me who due to lack of flexibility from lifting (and not stretching properly) are utterly useless for quite a while.
