Its a figure of speech and di pud mao ang buot ipasabot ni insect111. Ingon siya if you want a real upgrade, change the power supply kay ang Imaster PSU can only support videocards that is 3 steps higher than the onboard.
Imaster is not true rated. If in case mu palit ka ug mas taas na videocard like HD4870 or 9800GT, di na kadaog ang Imaster or worse, gub-on pa gyud na imo VC.
