I quite like that spec cookeh, and £1000 Max works, less if possible though as I'm budgeting for a Monitor, PS3 and 52" HDTV aswell. New Job, So I want to buy new toys to enjoy in my off time.
I wont be buying until the end of the month. So this week only offers may change for the better or worse! but that's fine.
With regards to the spec, what I may do, considering the amount of HDD space in the Fractal Design case(Which has to stay

) I may get the faster 1TB drive, and just put another drive in as I need the space. Similar to my idea for a second graphics card if the need arises. Reason I went with the initial CPU, was its guaranteed 4.8ghz, And I really want that 4.8ghz, I dont want to end up spending all these pennies and ending up with a lemon of a CPU.
If you had the choice with the PSUs, Which would you go for? the Corsair I spec'd initally or the XFX one you spec'd. As I'm happy to go with either if there's a benefit. If the only difference between the two is the fact the corsair is modular, I'll go with it. but if the XFX has more stable rails or something, I'll drop modular for stability.
As for the graphics cards, Thanks for the links. I think I'll look at some benchies, of the cards mentioned, and pick a winner for the spec above.
