My experience with my 1100T when I was using it on a DDR2 platform, It was decent, even in gaming with DDR2 800mhz. Since I moved to a newer board with DDR3 memory I didn't notice much improvement over DDR3, Only thing I noticed that was an improvement was on the DDR3 1600mhz ram I can OC the CPU-NB higher and gain more performance over the DDR2 memory where I could only get 2400mhz stable. DDR3 with a CPU-NB at 2899mhz I noticed a big difference not only in desktop usage, but in games the FPS gains were their.
