Gameplay FRAPS runs are always likely to throw up inconsistancies, simply because the runs cant be 100% identical.
For instance- a comparison in BFBC2 between
Techspot and
Hexus (review that went up today) benches
Given that the test systems are fairly equal (Techspot Core i7 965 @ 3.7, 6Gb DDR3-1600CL9 and Hexus Core i7 965 @ 3.2 w/turbo enabled, 6Gb DDR3-1066CL7) , identical drivers, both benches were gameplay runs recorded with FRAPS ( 60 seconds for Techspot, 30 seconds for Hexus) and both used identical maximum quality settings with 4xAA/16xAF...
GTX 480 ( 68 fps TS, 68.8 fps Hexus) -remarkably consistant !
HD5870 ( 66 fps TS, 62.33fps Hexus)- likewise
HD5850 ( 56 fps TS, 53.27 fps Hexus)- also fairly close
GTX 470 ( 47 fps TS, 53.4 fps Hexus) - ?
Regardless of the results, I'd still put more faith in user reviews -newegg and tech site forums, preferably with proof of ownership- than a fps pass. I've gamed with three of the four cards and found all to be more than able at the job.
