sculpting is very slow

I bought a new computer just for this purpose (CG) a few weeks back and it’s over $1000. I have 3.40GHz i7-4770 CPU and 16gb of RAM, but whenever I go into sculpt mode, it’s like I’m on my old Toshiba laptop that was 12GHz and 3 gb of RAM. What is going on? It’s so frustrating because i can barely move the mouse after putting a simple line on a 100-1000 vert mesh (without dynamic topo because that’s even sower). I’m so confused and upset as to why wouldn’t it work.

Please don’t cross post.
