So after sending in my 2nd(!) 7900GT that has gone bad back to XFX this is what they come up with... This is unbelievable. The 8600GTS performs worse than my 7900GT and they want 150$ to upgrade to an 8800GTS??? Also it says in their RMA page that I signed that if the current card was not in stock that they would send me a replacement with equal or better performance. What do I do? This is what I have written so far: Any more ideas what I should write?
