Is this build worth the £1300

[Jupz]

Hi well I was looking to build my first gaming pc and the grand total came to about £1250 ($1887) and was wondering if its too much too spend on a gaming pc. I mean I would like a pc that would be able to run all games including upcoming releases on very high or ultra but wondering if maybe I just switch to something cheaper like a gtx 770 and a mid tower case or something like that. What do you think ?
