Hey guys first time posting, long time lurker 
I have an around 700-800 pound budget as I really want a pc that will last a good bit. I study comp science so I can get the OS free, happy days
I also have a keyboard, mouse and crappy dell lcd monitor from 6 years ago which Ill upgrade later.
Was thinking about getting the 'Titan Triceratop' with a gtx 570. http://www.overclockers.co.uk/showproduct.php?prodid=FS-179-OE&groupid=43&catid=2040&subcat=1444
I was thinking maybe in the future when programs/games start to get a bit out of my league I could stick in another GPU and run it in sli?......Would it be possible with that set up?
If not could you spec me a pc around that budget range that would?
The reason im selecting the pre built first is I'd be worried about f-ing up the build process or overclocking as its costing me quite a bit. But my friend said your first build feels 'better than sex'...so im a bit torn. Mind you he likes sticking his 'harpoon in the whales' if you catch my drift.
Thanks guys any help appreciated!
