Hello. I don't know much about computers hardware-wise. I'm looking to put WoW on the highest level graphics-wise, and am aware that most of that game relies on the CPU and RAM. But regarding the video card, I'm not sure on what I'll need in relation to my specs. Budget=relatively expensive. Specs= http://h10025.www1.hp.com/ewfrf/wc/...&cc=us&lang=en&os=2093&dlc=en&product=3644705 I'm not settling for less, I plan to replace the 3gb with 4 2gb sticks (8). Will I need another motherboard for this video card?: http://www.newegg.com/Product/Produ...code=19-2776685&DEPA=0&refer=channel&CMP=OTC- Any advice will be appreciated. I'm very new in the upgrading realm. Would I be able to put that graphics card in my system as it is? Is there anything else I should be putting in my computer?
