Hello guys today is a somewhat bittersweet day. I got my M18X replacement for my M17X R2 I7 740QM 6GB ram 500GB HDD 5870m crossfire 1440x900 screen. They sent me a M18X 2630QM 8GB ram Dual 500GB HDD, GTX 460m sli. I know the videocards are a bit of a downgrade, but I could never get crossfire working in the R2, so I wont know the difference lol. Overall I am very happy with the laptop, and I must say I like it more than the R2, the palm rests feel so much better, and I know the screen is no comparison to the RGB, but I did not have that nor did I ever see one, so this is a big improvement to me. I also love the HDMI in, saves me from having to buy a monitor, because there where some games for PS3 that I wanted to check out. So do you think its worth it to overclock these cards, and is the performance of them comparable to the 5870m or are they alto worse.
