HEXUS has posted a review on the Leadtek PX7800 GTX TDH MyVIVO Extreme 256MB and SAPPHIRE RADEON X1800 XT 512MB video cards

What we've learned today is that both ATI and NVIDIA's partners know how to put a decent package together. Both cards, although expensive, offer something the other doesn't, and neither is a bad buy. That's not a review cop-out; it's the plain truth.
