Higher memory bandwidth = Higher resolution in Dolphin

I second this
GTX 650 Ti Boost has 144 GB/s memory bandwidth , AMD 7850 is also good stuff (153.6 GB/s)
That makes sense. Do you know what NaturalViolence was talking about with the AMD overscanning?

Well, we didn't know what your specs were in the first place and how you use it, but you seem to have done your research.
I asked what your PSU was to help you, people generally underestimate the need for a quality PSU and purchase cheap PSU's that output too little Watts sometimes. They usually buy too much though.
The 650Ti Boost would be a better choice and should be able to handle that 2xIR + 4SSAA in most games except the graphical intensive ones.

That's understandable. I threw my power consumption considerations out there so people wouldn't recommend something like a 7970 or a GTX 690.
So if I want to run 2xIR + 4SSAA, I need at least a 650ti Boost (or a 7850, I guess). Earlier in this thread, admin89 said that 4xIR is the same as 2xIR + 4SSAA. If that's true and 4xIR requires less GPU power, wouldn't that be a more optimal performance goal? I'm not set on 2xIR + 4SSAA as my minimum performance goal because I don't know enough about Dolphin to do so. I'm still trying to figure out what I should be shooting for.

It's all about the image quality you're after. For most people, 4x IR does the trick. Perhaps one of us could give you some screenshots at various settings so you could determine what looks best to you? If you have any games in mind specifically, just throw them out.

The games that I'll be running are:
(what I run right now)
Windwaker
Twilight Princess
Mario Kart Double Dash
NHL Hitz 2003
(what I'll probably/hopefully be running after the upgrade)
Mario Galaxy
Skyward Sword
Mario Kart Wii

They're not the same thing. They just have roughly the same performance hit since they both cause everything to be rendered at 16 times the native resolution.
SSAA uses a different scaling filter. It's generally better in terms of image quality.

In general AMD GPUs are more likely to have issues with using an HDTV. It's really a luck of the draw type of thing that depends on your gpu model, driver version, and HDTV model. The most common of these is an overscanning issue that causes black bars around the image (the image doesn't fill the entire screen).

That's not entirely true. It has a larger effect on performance than it generally does in PC games but it's certainly not the only factor that effects performance.

Thanks for the response.
Regarding what you describe as the overscanning issue, I think I know what you're talking about. It shows up when you use the HDMI output. There's actually a way to adjust that in the Catalyst control center. If you type "overscan" into the search bar, it'll take you to a screen called "Scaling Options (Digital Flat-Panel)". The default is something like 5-10% (I don't remember, exactly). Just set it to 0% and you get rid of those black bars. Why AMD chose that as the default, I don't know. I found it annoying, too. But a google search brought up the solution.
