That's a 6600nu (vanilla)? Because if it is, I **believe** you can flash it to a GT, and I would also get a good cooler, something like the Zalman VF-700cu.

Also have a look at different drivers. The newest ones don't mean they are the best, I'm currently using the 81.95's because they seem to work the best for me
