Nvidia partners are still waiting for any serious quantities of the new single PCB GTX 295 card. The normal, dual-PCB 295 cards are selling and they are available, but when it comes to single PCB cards, some vendors have them, but still not enough.
The card should have chips that will have less leakage and it should allow better clocks and stability, but again, it’s a minor change, not a great one.
There are already some listing in our price search engine which you can check out here. Prices are quite the same compared to the double PCB version. At least one Zotac single PCB card at €408,75 seems to be available.
