Thats a real shame, for less money and slightly more horsepower you could have ordered
XFX 5830 £83.99.
Given ATI/AMD's numbering system for the 5xxx series of cards, you can pretty much tell it performs better than the 5770. Not by a huge amount, but games like Crysis where every FPS matters when playing at the 1920x1080 resolutions, this card certainly proves it worth at that ridiculously low price.
I personally wish I saw this offer 6 months ago, but then this would be true of many cards i've oggled over the last 6 months.
