1. i also dont know wat is dedicated memory, maybe is the own gc memory
2. shared memory is the memory that ur gc take/share from ur RAM, so ur RAM will be -64mb
3. 6150le i've never heard be4, and also i didnt see any 250MB gc available, as most of them r 128 > 256 > 512 > 1024, no 250mb exist

if u want a good card, u can state down ur budget and purpose, and here hv many kind forummer who can help u always

student?? me too how old r u?? haha, out topic....

actually, increase ur RAM memory wont increase ur shared memory, for wat i know lar, 64mb is the maximum memory it will share, and some forummers told me that the gc only will share the memory when it is needed, just like u borrow things from ur frend, after use then gv it back...

since u r a student, then how much budget ur parents gv u for buying gc?? maybe u can go for work for some extra income, holiday coming

O.o i think he didnt use it for gaming, just some movie or msn or friendster....

just my 2 cents
