The 890GX chipset offers x8/x8 bandwidth. The 890FX chipset offers x16/x16 bandwidth, which, if you're using a super high end card like the HD 5970, is essential, but for anything less than that like the HD 5870, there's not much point upgrade as there isn't much of a performance impact.
Well,going from dual 8x to dual 16x won't give you a noticeable boost unless you play at a resolution like 2560x1600 with AA/AF on.
Well,that's not exactly true,because a "single" 5970 will run at 16x on a motherboard which supports CrossFire at dual 8x.
