GT 540m ? I've recently got Samsung RC530 with i5, GT540m, 8 giga ram. I'm very happy with it. I can run Skyrim, BF 3 easily on high. However I've read somewhere here that there is problem in D3 with OPTIMUS technology (you have system and nvidia graphic cards on the board and you choose which one to use). Is it true? Is it actual (it was post from last year)? Ive seen on YT people playing D3 on high with this card.
