Is there a possibility in the GT680 to put an ivy bridge processor and if yes then when would a BIOS version with such a support be available?

Hi all, I would like to know if I own a 7970m card with 015.017.000 vbios and a sandy bridge motherboard which doesn't support Optimus, can I run this card without upgrading the vbios? If this vbios doesn't work with my motherboard then what's the best vbios I should upgrade? Thanks!

Hi all... I own a MSI GT680 and I would like to upgrade the GPU. My questions are: Does the 7970m and GTX675m (2 or 4 GB) works with this notebook model? Which graphic card is better in terms of performance and issues for this notebook model - 7970m or GTX675m? Do I have to buy a new heat sink or does the stock one from GTX460m fit both of these cards (7970m or GTX675m)? Do I have to upgrade the vbios in these cards in order to make them work on this notebook? The original PSU is 150W. Do I have to buy a new PSU with 180W or 220W? Thanks for your answer.
