G450 dengan K40AB sama je..G210M lebih kurang je dengan 4570, dan takde advantage C2D pakai DDR3

Persoalannya sekarang sama ada nak pakai Intel or AMD
Dan warranti asus 2 tahun versus 1 tahun lenovo

Bottleneck dalam kedua-dua sistem ni bukan sebab processor, tapi jenis VRAM
512MB DDR2 memang tak cukup bandwidth supply untuk 4570 dan G210M
Sebab tu performance naik mencanak lepas oc memory clock

Nak tengok beza VRAM DDR2 dgn DDR3 test Studio 15
Baru nampak beza antara 4570 512MB DDR2 dengan 4570 512MB DDR3

So pilih je mana yang berkenan, dua2 sama je..

Personally ikut pengalaman aku,
Intel lagi laju processing tapi AMD lebih responsive

Sheikomatic...
Takde beza ke kalau C2D guna DDR3 RAM? Maksud ko speed RAM akan run ikut DDR2 je ke?

FSB T6600 hanya 800MHz, maksudnya base clock T6600 cuma 200MHz
Pakai ram DDR2 400MHz pun dah cukup, tak perlu nak pakai sampai DDR3 1066MHz

Sistem FSB tak boleh full utilise even DDR2, sebab tu performance naik kalau oc FSB
Sebab memory bandwidth lebih tinggi
Hanya sistem dengan QPI, DMI atau HyperTransport shj yang dapat full utilise bandwidth DDR3 tanpa oc

Kesimpulannya skrg mudah je, ram DDR3 kat Lenovo G450 langsung tidak memberi apa2 advantage berbanding DDR2
