You are overspending on the CPU. It is generally accepted that a dual core will not be significantly slower than a quad core in games. For just over £50 you can get an E5200 which can be clocked to around 4Ghz. This saves you £70 which can be used to get a far nicer case (that Asus looks way too small, and doesn't take 120mm fans) and, more importantly a 4850. The 4850 will absolutely dominate the 8800GT, even coupled with the slightly cheaper CPU.
Also, if you get the cheaper CPU you can get a much nicer mobo, which will be important for clocking the 5200!!! If you dont need a PSU I would go with:

Along with the E5200. For under £400 that is simply fantastic, and will really outperform the spec you posted above. You get a better case, motherboard, more RAM, and a far better GPU without really losing out on the CPU.
EDIT: Spend the remaining few quid on an Akasa 965 heatsink. I got one the other day and it is far more efficient than the Intel stock cooler, and is quieter.
