Hi there rory5401
I would say yes, but you might run into some problems.
The rest of your system looks good, except when I see the 3450.
The 3450 is an extremely weak card. I WOULD HIGHLY RECOMMEND UPGRADING
If you can't there's options. But on the bright side of things, WoW and those types of games are fairly easy to run.
Just play around with the settings and resolution until you get the FPS you want.
Happy playing!
