Ok well this is my first post, im not sure how friendly you guys are to complete and utter noobs but here goes, hopefully someone will be nice 
Ok i have about 1000-1100 to spend on a new PC , maby more depending on how much i sell my laptop for (dell xps m1710) ... The main reason for me wanting to do my first build is that i play a lot of xbox 360 and want a new screen capture device, at the moment i use something called a 'hauppauge hd pvr' and i want to upgrade to a "black magic intensity pro" . So yeah the BMI pro has quite specific components that it likes and dislikes so i want the pc to cater mainly to that, rendering hd video files in sony vegas , and the odd gaming session ... other then that ill be using the pc for university work, browsing etc.
