Congradulations on your new card.
Yes it was, I was just going to say that
You can flash the BIOS to a 6870, but it's not going to have the performance of a 6870. The 6950 to 6970 is a diffrent matter.
Here you can read to what frequencies they got their 6850.It's a great review.http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/37499-hd-6870-hd-6850-vs-gtx-460-1gb-overclocking-study.html
What is strange, that in diffrent sites, the Benchmarks, are VERY diffrent, some show the 6850 faster and some show the GTX 460. From what I have seen the 460 OC a little better, but not that much.
I think you shuld go a little bit lower(weird ah) something like 900/1100 and try to run it a closest to stock voltage, but thats my opinion. I dont think 5-6 (maybe) FPS is worth to go over these limits.
