I got some great advice on these forums and built my first ever system which has served faithfully these past 4 years. With games like Skyrim and BF3 now out it seems a good time for a new machine. It will be used primarily for gaming but will also need to be able to deal with some 3d modelling and photoshop. My budget limit is £1000, I put together a sample spec for a starting point, I'm completely out of date with my knowledge of components so try not to laugh to hard, far better to be the fool on the forums than the guy who threw away money on an impossible build.
I'm pretty certain about having a 580GTX and the i5 processor. Everything else can go, I would like a modular power supply, I would like a SSD ideally 128GB but 64GB may be more realistic and I would prefer an Antec case. I don't need a copy of windows and I'm recycling my current 500GB drive until prices drop. I do plan to overclock the processor ideally to a little over 4GHz but nothing else and I don't plan to go dual graphics cards at any point.
Thanks in advance for your advice.
