Graphics cards and power requirements?

PCI, AGP or PCI Express?

Please provide your system's specifications.

If it's a pre-built system like a Dell, HP, Acer, Gateway, etc. then provide the brand and model number.

First of all what is your rest system and what brand if your power supply?I ask about the brand because if it is a "no name" power supply you cant trust it very much.But generally i dont think you can go very high on graphics card performance with this power supply.

Its an HP a6130n and a PCI express

The ECS MCP61PM-HM (Nettle2-GL8E) motherboard's PCI Express version is 1.0a.

Graphics cards based on PCI-E 2.0 appear to run without problems in a PCI-E 1.0a motherboard slot.

Some graphics cards based on PCI-E 2.1 have caused compatibility issues when used in a PCI-E 1.0a motherboard slot because the PCI-E 2.1 version that was implemented didn't fully follow the PCI-E 2.1 specifications.

Choose one of the following based on desired performance and budget requirements.

NVIDIA makes PCI-E 2.0 graphics cards. The following low power consumption cards should work with your system:

GeForce 210
GeForce GT 220
GeForce GT 430
GeForce GT 440
GeForce GT 520
GeForce GT 530

AMD makes PCI-E 2.1 graphics cards. The following low power consumption cards may work with your system:

Radeon HD 5450
Radeon HD 5550
Radeon HD 5570
Radeon HD 5670
Radeon HD 6450
Radeon HD 6570
Radeon HD 6670

Which brand of Radeon would work best for my need? Sapphire, XFX, VisionTek, ect... I'd mainly use it for web and watching vids. I mainly want a card with HDMI output that supports audio.

All of the Radeon HD graphics card I listed have an HDMI port and an integrated HD audio controller.

The Radeon HD 6670, Radeon HD 6570 and Radeon HD 6450 adheres to HDMI Version 1.4a.

The Radeon HD 5670, Radeon HD 5570, Radeon HD 5550 and Radeon HD 5450 adheres to HDMI Version 1.3.

The SAPPHIRE 100323L Radeon HD 6570 1GB DDR3 PCI Express 2.1 x16 HDCP Ready Video Card for $74.99 is an excellent HTPC graphics card.
