Built up my PC a little over a year ago. Pretty pleased with how "future proof" it is too. i5 cpu overclocked at 4.2 will do me well for some time. Got 8GB or RAM atm and I can go up to 16GB with my mobo. My GPU can play current games easily (and most in full settings) and I have a second one (they fucked up and sent me 2 but only charged me for one ) that I can set up in Crossfire when I need MOAR POWAH.
New Update - July 26th 2015 - Judgment Day 2007 PPV Ramblings!!!
My PC is about 3 years old but barely use it cause it's fucking up and on it's last legs. I'm going to have to put all it's files on a USB to keep any important documents before it completely dies on me.
I've had mine 7 years. Cost over £1200 in 2006 and my Dad paid for it outright, and then I paid him £10 a week for the next two years and a few months. I was working for him full time and had too much money at the time as well which always amazed me he only wanted £10 a week, not a single complaint though.
Still works flawlessly. I'm not really a gamer so as long as it runs movies/music/internet I'm cool.
I can remember buying it and it's 300gb memory, and the man who sold it told me there is no way I would ever fill it. About 5 years ago I had easily filled 200gb with music and kept having to delete everything I watched.
Still, for 7 years worth, it's done it's job brilliantly. From when I bought it up until about 2010 I used it just for films/music/internet and also had my television hooked through it along with my Playstation, then for the last 3 years I've used it for work as well as the other three, and have it connected to the super-large TV on the wall and watch movies/TV nightly. It's paid for itself over and over.
I reckon if I wiped it completely, cleaned it thoroughly I could easily get £400 for it. Impressive given it came with a modern for the time monitor, stacks of re-burnable DVDs and all sorts of printers/scanners as add-ons.
Along with my iPad and my huge telly, it's the one thing that I can always say I have got my moneys worth.
I'm expecting to keep using it as well, not worth fixing what isn't broken. I don't game, unless it's Football Manager a few hours a month, so as long as it work it will do me.
