Thanks once again
kharma45 for being so awesome in helping me decide on my order.
In the end it's costing me just over £900! Welp! Effectively double what I originally intended to pay and over my max budget but fuckit!
I added a CPU cooler, went for a more expensive but quieter case and took your advice by going for the AMD Radeon HD 7850 2GB, plus I chucked in a webcam too.
I told the sales guy who rang me back to confirm that they'd sorted out the site issue so I could place my order that even though I'm 47 years old I feel like a four year old waiting for Santa! I'm so excited now I want to jump up and down on the spot like an over excited child!
Given that this is the pc I've been using for the last ten years I think I'm entitled to be excited:
Windows XP
Intel Celeron CPU 2.53 GHz
759MB RAM
Intel 8245G/GL/GE/PE/GV Graphics Controller
Feel free to laugh/wince/cry/have your head explode at those awesome specs!
