I got them both! The extra RAM on the laptop is great! I just got the video card in the morning, even though the website said 2.0, it was actually 2.1... I installed it anyways and it seems to be working fine. My only concern is that I opened Catalyst Control Center thing and it says that the temp on the card is 77 ºC (170.6 ºF). ;x That sounds really high to me, is that normal? o.o I cleaned out all the dust when I installed the video card, so the fans and everything are really clean.
Video cards run hot. 77 is a low temp for a card. If you were pushing it, you would see temps hit low 90's. The main thing to watch for is the temp on your CPU. If the card is hot and you don't have proper air movement in the case, or a heatsink not capable then your CPU might run hot. For the most part I don't think you will have a problem.
