Too bad for the 660Ti that you can get a 7950 for $17 more (actually less if you include that Newegg charges $7 shipping for most 660Ti cards). Each of those games you linked runs well on NV cards to begin with. It is no surprise the 660Ti can hang in there. Let's expand the average to include
15 games --->
8% slower than an 800mhz 7950. HD7950 has 40-50% overclocking headroom above 800mhz for
$317.
Exactly. As I said it before what made GTX460 a star was overclocking. HD7950 is exactly the same, even better. All these reviews pitting factory pre-overclocked 660Ti vs. an 800-850mhz 7950 are not giving the 7950 justice imo. This is like testing an i5 2500K at 3.3ghz and calling it a day.
It takes about 5 min to glance
at these 5 graphs to see how freakishly fast a 7950 gets at 1150mhz. It is
20% faster than a 7970 in BF3.
660Ti is 1 full class below. 24 ROP / 192 bit 1.5GB (?) vs. 32 ROP / 256-bit GTX670 2GB
7950 = 32 ROP / 384 bit 3GB vs. 7970 32 ROP / 384 bit 3GB --> slightly less TMUs of 112 and shaders of 1792 vs. 7970.
AMD is selling a slightly neutered flagship and NV is selling a 25% gutted card 670. NV card has worse overclocking headroom. An overclocked 7970 beats most overclocked 680s. The math can't be simpler here. BL2 makes the card appear to be worth $250 to some people though. That's a valid point.
