I have a ThinkPad T430 which I'm now typing this on. It's an i5-3320m
(vs your i7-3520m) with 12GB RAM and the same HD4000 class graphics, so
it's pretty close.

Am no expert, having only installed OpenBSD for the first time recently,
but played around with the staff settings when I couldn't use a browser
or play video at all well. Started with some values in a blog post on
the net from someone setting up a laptop, and ended up with:
:datasize-cur=8192M:\
:datasize-max=8192M:\
:maxproc-max=4096:\
:maxproc-cur=1024:\
:openfiles-max=32768:\
:openfiles-cur=16384:\
I have also set the following systcl values:
# shared memory limits (browsers, etc.)
# max shared memory pages (*4096=8GB)
kern.shminfo.shmall=20971552
# max shared memory segment size (2GiB)
kern.shminfo.shmmax=2147483647
# max shared memory identifiers
kern.shminfo.shmmni=1024
# max shared memory segments per process
kern.shminfo.shmseg=1024
# Other
kern.maxproc=32768
kern.maxfiles=131072
kern.maxvnodes=262144
kern.bufcachepercent=50
The large files numbers here are due to using syncthing, and (I'd guess)
probably not generally advisable. The other stuff is quite likely to be
inadvisable or just plain wrong (due to my inexperience), but it has
given me a responsive system when using Firefox / Chromium, playing
video etc.

Although the login.conf and sysctl settings made the most difference for
me, I do have a smoother experience using the intel driver than the
modesetting one. It's especially noticable when playing video in
Firefox, and dragging the browser window around on my XFCE desktop. The
intel driver happily plays the video smoothly as the window moves
around. The modesetting driver wouldn't do that for me.
I have the following at /etc/X11/xorg.conf.d/intel.conf
Section "Device"
Identifier "drm"
Driver "intel"
Option "TearFree" "true"
EndSection
Hope some of this might be useful!
