Unless your PC has suddenly imploded or is so slow it is not functional for your purposes, it seems pointless to get a new PC now when the first new architecture AMD processor since the Athlon 64 is being released in a few months.
Sandy Bridge will go down in price when Bulldozer is released unless Bulldozer is slower than a Phenom II.
It is not the first time that Intel has reduced prices with a new AMD CPU release.
Maybe you should have seen the price of the Core2 quads tumble when the Phenom II X4 processors were released. The Q9550 was well over £200+ until the Phenom II X4 955BE came along. Then all of a sudden it dropped to around £160.
I nearly considered getting one myself
IIRC. However,my Shuttle would not work with 45NM processors.
The same goes with the whole Core2 duo E7000 and Pentium dual cores which dropped in price massively when the Athlon II and Phenom II X2 was released. The E7000 range was more than £80 to £90 until the Phenom II X2 was released. The lower end ones disappeared and Intel dropped the price of the higher end ones to replace them.
Intel released the
multiplier unlocked Pentium E6500K to counter the Phenom II X2 BE in the Far East.
The Core i3 dropped below £100 because the Athlon II X4 and Phenom II X3 were competing with them in a similar price range.
The Phenom II X6 comes along and then the price of the Core i5 750 and 760 started dropping too.
Both the Phenom II X6 1055T and Core i5 760 were around the same price for months.
