Read about the 2D/3D clock prob. That seems to be fixed with a bios update.
But I'm wondering why the review sites does not faced such issues.

The card looks just awesome & has great cooling :

But if you want to be on safe side then go for MSI GTX 260 OC edition but it sports with stock cooler so the temp will be 2-3C higher
You can also consider Zotac GTX 260 which is only Rs. 10K now
