Hi I'm new to installing parts in computers and I want some advice, I'm planning on getting this computer

And I was wondering if I could install either the GTX750TI or the GTX750? And if not what graphics card would be a good one to go for? Thanks in advance, sorry if this question is pretty obvious.
