I'm buying a Gateway SX2802-03, which incorporates many nice features for a great price. The one enhancement I think it needs is a video card to replace the Intel X4500 on-board accelerator that comes with the system. The system's power supply is rated at 220w and I find that most video cards require 300w or higher. Also, whichever card I find will have to be low-profile, and, ideally, cooled with a heat sink rather than a fan. I'd appreciate any information to help me with my selection.
