I'm currently looking to upgrade my Powercolor X1600 Pro 256 Extreme Edition (X1650 chip set I think) card and I'm looking at the X1950 series. Now I've stumbled across 2 which are similar price, GeCube X1950XT (256) and the HIS X1950Pro (512) IceQ 3 Turbo. Both of which are around the £140 mark. Considering the XT range is of a higher spec than the Pro, what benifits does the IceQ 3 range have?
