Hello! does anybody mind helping me chose the correct pc

Hello, I'm currently considering a PC for what I believe is a bargain. I'd really like some opinions on it's specs and what are the most demanding games you think it could possibly play (Just to get an idea of how powerful it is). Some basic specs are:
Intel Core i5 3570k 3.4Ghz Processor
16GB RAM (It is two 8GB RAM sticks but I'm planning to use four 4GB RAM sticks to make use of Quad channel mode)
120GB Solid State Drive
1TB Hard Drive
GeForce GTX 750 2GB Graphics Card.
(The casing is a 'Chillblast CoolerMaster Gaming Case')
I'm getting all of the above for £550

Also if there's any recommendations you have please feel free to tell me them :). Oh and I will using this PC for Gaming and Video editing !
Thanks, Dan :)

You can use the GTX 750 ti too
