Is there such a thing as a good low profile card? I mostly play an MMORPG called Vindictus. I don't know how graphically intense the game is, but the 8400 gs can only handle 3/10 on the auto scale. This is a low profile case and the 450w psu is sitting outside the case, so a full card hanging out of the open case is an option if necessary. It won't win a beauty contest, but it will work. I have tried to plug in a Sapphire hd 5670 PCIe 2.1 and found it to be incompatible w. my board. I only have a PCIe x16 slot, so I am limited to the PCIe 2.0 cards.
