GPU upgrade boosts clock speeds and increases onboard memory from 256MB to 512MB.

The new GPU features higher clock speeds and support for up to 512MB of GDDR3 memory. Nvidia has increased the GPU clock speeds from 430MHz to 550MHz, and the card can now handle up to 512MB of faster 850MHz GDDR3 memory thanks to a new dual-slot board design. The core clock and memory bandwidth increases will provide immediate performance benefits over other video cards in the latest, hardware-intensive PC games including F.E.A.R. and Quake 4.

The GeForce 7800 GTX 512MB has a $649 MSRP from Nvidia, but actual retail prices will vary since the GPUs have to pass through a board manufacturer and a retailer before it reaches the customer.
