The Hexus crew have posted their GeForce 7800GTX preview today. NDA? Never heard of him... ;)

"All-in, a solid improvement to an excellent architecture. NVIDIA balance ALU increases with ROP considerations to create a formidable pixel pusher that currently has no equal. 7800 GTX boards can be bought from today for a UK retail price of £369. That's only some £70 more than a 6800 Ultra (15%), for a rough 40% increase in performance, should your wallet be up to the task."
