7800GTX works on 24 Pixel Pipeline and 8 Vertex Shader units while the 7800GT works on 20 Pixel Pipeline and 7 Vertex Shader Units. Obviously the card is inferior to 7800GTX but the price difference is worth considering. The 7800GTX currently costs around $542.00 and the 7800GT around $449.99, $100 difference between their prices. The 7800GTX is truly a beast but 7800GT provides great performance/price ratio to those who are neck to neck with their budget.
