I got the 970/7125 combo in December and am really loving it but a larger than expected bonus from work and tax return have me thinking about maybe selling the 7125 and upgrading to the 7500. I have not seen any one who has upgraded that has the 970 and I was wondering if any one else who has the 970 had made this leap. Even if you have the 990 any input about the improvment that the 7500/7700 has brought your system over the 7125 would be greatly appreciated.
