common guys, look at this realistically. playing a game of video cards it's always win some loose some. sure in some areas the 9800pro is better than a 6600, but in some areas it isn't. a video card's performance can never be judged by a single game alone. not to mention, if the user were to want the 6600 for linux, it would spank the shit out of the 9800pro in ALL areas in linux.
i'm not saying he is or isn't, but it irks me to ever hear/see someone say "this card is better than this card". if it were that simple, we would all buy the same cards, but it's nothing like that.
not pipelines alone, not clock speed alone, not memory latency alone, and not even memory amounts alone can determine what will be an all-inclusive better video card. the exact same pipelines, speed, memory, even PCB, clocks, and HSF with 2 different cores will change performance depending on the game/application. it doesn't necessarily one is better than the other, but just because a video card has 8 pipelines compared to 4 of another card doesn't mean it's twice as fast. nor does it mean that when you've got twice the clock speed, or twice the memory... and i haven't even touched on vertex shaders or new technologies like sm3.0.
on a small final note, not even the fastest video cards out right now have capped the bandwidth of agp8x pro, do the interface, be it peg or agp should have little to no impact on performance. agp8x is just now beginning to be matched on its bus speed, which is why peg is coming out. they dont introduce new technologies when it's already too late
this is similar to the myth that SATA drives are faster. no, they aren't. not at all. the interface of PATA is 133MB/s and the fastest a 7200rpm drive can transfer data right now is somewhere between 60-90MB/s... clearly under-cutting the performance of 133MB/s PATA. slapping a bridge on it to allow it to transfer at 300MB/s between the drive and the mobo does as much good as having a 1000mbit connection between your computer and your cable modem, it's not going to allow a single bit of increase in speed over a 100mbit connection... unless of course you can download at over 100mbit/s
