That sounds good. I'm not sure how the GT 630 will perform in games but the CPU on it is snappy.
I used to run WOT fine on my OC'ed 4850 DDR5 but I can't find an the desktop equivalent of the 630M but basing from nVIDIA's spec sheet (http://www.geforce.com/hardware/desktop-gpus/geforce-gt-630m/specifications)
I feel that it it could play WOT with low or low-med settings without stuttering depending on how many tanks are on the field.
There have been some game benches from this site: http://www.notebookcheck.net/NVIDIA-GeForce-GT-630M.63761.0.html
where you can take a look at some of the scores they got from that GPU. Some games actually play smoothly at med to med-high.
I can't comment on the other games as I haven't had any experience playing them
