SAPPHIRE RADEON HD 2600 XT

"The Sapphire Radeon HD 2600 XT is compared to the XFX GeForce 7900 GT. The Sapphire Radeon HD 2600 XT RV630 GPU is clocked 32% faster, has 40% faster memory and 96 more Pixel Shaders compared to XFX GeForce 7900 GT. Another advantage the Sapphire Radeon HD 2600 XT has is GDDR4 memory but unfortunately it also has a major disadvantage which is the 128Bit Memory Interface, how will this effect performance?"
