Not as good as the 20% deal, but Dell are offering i7-860 equiped Vostro with £70 off + £50 off coupon if the machine costs £479 +
Coupon code is : G7FPTX83H50S17
I chose the £439 base spec Vostro, then upgraded to 4GB of 1333MHz RAM and IEEE-1394 firewire card to take the price up to £479.
Final cost is 504.08
Quidco also offer 5% = £478.88
Like I said not as good as the earlier 20% off deal, but still a great price for an i7-860 based system.
USEFUL COMMENTS PROVIDED BY PLAP:
"If you want the machine with 4Gb DDR 1333 RAM this is a better deal than the 20% offer:
"Creative PCI Express Sound Blaster X-Fi XtremeAudio [Included in Price]" is included.
This sound card was not in the 20% offer (that just had the on-board sound only by default) goes for and approx £44 on other sites (ebuyer and the likes).
"Logitech Wireless Keyboard & Mouse Pro2800 Black UK&Irish [add £14.03]"
because this adds only £4 to the pre-VAT price (Dell glitch), costs about £35 incl. VAT in other online stores.
Make sure to select Windows 7 64bit (32 bit cannot address your full 4Gb of RAM)
and if you go for 4Gb 1066 RAM there should be some cash left for the 20-in-1 memory card reader (not checked this myself, just puzzle until you hit the £479 treshold)
Don't forget Quidco or topcashback!"
