"uhhh no.
first of all, Xbox 360 and PS3 do not have graphics cards. they have graphics processors / GPUs built directly onto the motherboard, unlike PCs which do have actual cards.
secondly, the Xbox 360 and PS3 graphics processors are custom, they are not found in PCs even though DERIVATIVES of them are, or will be.
the manufacturing costs and retail prices of console GPUs and PC GPUs/graphics cards are structured COMPLETELY DIFFERENTLY. there is no comparison. console GPUs are manufactured in the 10s of millions, whereas highend PC graphics cards are manufactured in the tens or hundreds of thousands, or a few million at most. highend PC graphics cards / GPUs are at the highest possible specifications manufacturable, whereas console GPUs use new technology for the time, but do not push the limits of transistor amount, core clockspeed, memory speed, etc. no comparison."
your arguement is offically dead
voodoo pc now come with 2 7800 gpu's built in
NOWAY a 360 graphics chip could even compare with that power, yet guess what its 2 400dollar american chips put together
COD2 looked like it had 8x antaliasing for 360, noway can compare to 32x antaliasing
