The best upgrade card is the 7750 (800 MHz) version.

This will work perfectly fine in your computer which has a rating of 300W. It also does not need to have the power supply connected to it. You just install it on the PCI-E x16 slot and you are good to go.

I would suggest this to fit in the case

XFX 7750:

The height of the card should fit the width of your case at least 1 inch.

If you are seeking a newer card, you'd probably want to upgrade your PSU. I don't know if your Power Supply Unit is installed at the top or bottom of the case.

Hope that helps :)

That does help. I didn't expect the machine to have a lowish power rating since it's supposed to be a high-end set up.

I assume the PCI-E x16 slot is where my stock graphics card is installed?

I'm rather set on the 560 though, because it does seem to be exactly what I need, and not a thing more. Also, I'm used to NVIDIA and its drivers and what not.

How do I upgrade the PSU? It appears to be located at the back and on top.

Then you must find a PSU with at least the same measurements.

What you can do is uninstall the PSU (it may be screwed in, so you may have to unscrew it), take it out and measure it, then compare the unit with the measurement on the website.

Some brands you may want to consider is SeaSonic, Antec, Corsair.

You'd want at least a 450W or 500W system.

Seems like I'll be spending time with unclear rewards.

1. Will the radeon 7750 (800) be a sufficient upgrade from the gt 420?

2. Will it be a simple matter of unscrewing and removing the 420 and attaching the 7750 in the same slot?

3. I've gathered that nvidia updates its drivers more frequently and just generally has more support. Any caveats if I do shift to amd?
