Chaps,
I have 2 Radeon HD 6950 cards that i am going to sell in order to upgrade my system.
First up we have a MSI R6950 Twin Frozr III Power Edition. This has had the Shaders unlocked to HD 6970 levels using the officially released MSI Bios update and is a 2gb card. It is a stonking card and can be had for the princely sum of £110 plus £5 postage.
Secondly, we have a Powercolor HD 6950. This has been happily running in crossfire with the MSI with no issues whatsoever. However it has not had any shaders unlocked so is a great, standard HD6950. This can he had for the sum of £100 plus £5 postage.
If you want both i will do a deal for £190 plus £10 postage.
