'kay. I just waited hours for Rappelz (MMORPG) to download, install and patch. When I finally get into the game, everything is monochromatic and polygon-ish, instead of the smooth graphics expected, and half of the time it kicks me off before I can completely finish logging in. Obviously, this 7-year old hunk of hardware I call a computer is not up to standards. However, I need to know what to fix. I meet the minimum requirements for CPU and RAM, but I'm not sure about my graphics/video card. Judging from the issue, is a new graphics card what I need to fix the problem, or do I need more? Please help me, as I am very anxious to play this!~

Thanks in advance for helping a hardware-inept idiot.
