errr, don't cpu prices tend to fall over time? I suppose if you bought it in July it would have been cheaper???
Not in this case. The i7 920 should really cost £200+, but because it is going end-of-life and being replaced by the i7 930 then there are some amazing deals for the i7 920. Considering they overclock just as well as each other, going for the i7 920 now makes a lot of sense - even if its just going on a shelf for a few months. By the time July rolls around it is highly likely that there won't be any i7 920s left.
To the OP - Good luck, do you know what motherboard you will be going for when the time comes?
