Nvidia plans to release a new core codenamed D8M in September and that will be the company's debut in 65 nanometre parts.

Nvidia is happily selling Geforce 8600GTS /GS and it looks like G8M is the codename for its new 65 nanometre parts.

We should have more details shortly, but the irony is that Nvidia kept its mouth shut although it will be ready with its 65 nanometre parts shortly after ATI.

Even Nvidia's G86 and G84, both 80 nanometre parts, should outperform Radeon HD 2600 and 2400 cards.
