Spend the £20 more on a P5K-E, you'll get a MUCH higher quality board.
The QX9650 is VERY nice, but the "X" series are hardly ever worth it - soon the Q9450 will come out which is a "bit" slower (ie 2.66 GHz, 6 mb Cache), but will quite happily overclock well in excess of the QX9650 speeds.
I'd also get a "brand name" GFX card for the warranty, rather than going for a ScanFX thingy.
EDIT - £234 for a GTX?! It's outta stock, so i'm sure that it'll go back to £300-ish when it comes back in stock...
