Its hard to put a dollar value on performance, I guess that's why we review products. For you to decide if the performance gain is worth the cost. From a perspective where I truly liked the SlotA Athlon, I hated to say bubye to it, but the performace is there with this upgrade. Some people may decide a CPU and motherboard upgrade is too much, but consider the cost of the cutting edge video upgrade. I paid $429 to upgrade from a Voodoo3 2k PCI to a Radeon 64 VIVO. While it was worth it in features, some video cards may charge you upwards of $600 just for more fps. You can easily upgrade your motherboard and CPU for less than $300 in most cases and see the same gain.
