it seems that a 64mb x700 is quite inhibited compared to a 128mb x700, considering 3dmark05 anyway. i have a 1694wlmi with a 2.0ghz P-M, 1GB ram, and 64mb x700, and the most ive managed to get in 3dmark05 is around 1700 with the new catalyst 5.8's. however I see other posts here, even with people who have a 1.6ghz P-M with a 128mb x700, that get around 2300 or so on 3dmark05.
so the 64mb of memory must be a substantial bottleneck when it comes to extremely intensive graphics like 3dmark05. but i guess in games at present, they're not demanding enough to see that much of a difference? i never knew VRAM was that significant though, cause 600 or 700 3dmarks is quite a difference.
im curious what other owners of 64mb x700's are scoring in 3dmark05? just to make sure somethin isnt screwy with my laptop
