So, i just bought myself a new computer. I needed it for recording videos and a little bit of gaming. I knew it had a really bad integrated graphics card , but since it is DT (desktop) build, i found out it's pretty hard to upgrade due to its size and 305w psu. I'm planning to play and record minecraft, counter strike global offensive, not the huge titles. However in my free time i would also like to play a game like Battlefield 3 (doesn't have to be on the highest settings, even medium is fine.), will i be able to with that graphics card?

Is it possible to upgrade that computer with this particular graphics card : http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1073&pid=1258&psn=&lid=1# ?

I know that it needs a 450w psu, so i'm wondering if you are able to change it, and how.

Will the HD 6750 fit the case? If not, can i change the case to a MT?

Also, if that card wouldn't work with the DT GX620, what other good card could i buy for some gaming on that exact computer?

P.S what about the HD 6670 1GB ddr3, is that better? It only needs a 400w psu.

-Thank you for reading, hopefully you can help :)
