AMD mopped the floor with Intel fromm 1999 to 2005 in performance. The Athlon 2800+XP was clocked at 2.08 GHz (released in 1999) and had the same level of performance as the Pentium 4 clocked at 2.8 which was released in 2000, then came along the Athlon 64 2800+ which had twice the performance at 2.0 GHz than the Pentium 4 @ 2.8 Ghz . So yes, AMD kicked Intel's ass. And for some more info the Core I7 is a reverse engineered Nehalem FX architecture that Intel obtained by purchasing the Nehalem microprocessor fabrication plant from AMD (where the older FX processors were manufactured and where the I7 was born) but it's funny that after the Nehalem plant created the first I7 Intel shut the plant down shortly after. And as for the ATI HD5870, it was designed to compete with the short lived GTX 380 (which it kicked it's ass), the GTX 480 came March 26, 2010 the HD 5870 came September 22, 2009.
