ATI Pro9800 Ultimate & Catalyst 5.4 questions

[goodstuff]

I just upgraded my PNY GeForce FX5200 Ultra to a Sapphire ATI 9800Pro Ultimate. I usually don't play any heavy duty 3-d games so I always left the advanced settings as they were. Now with the new ATI Catalyst driver there are all kinds of settings that I'm not sure what to do with. I normally want to leave the settings as best for my regular tasks like Photoshop, image editing, etc. Under the Catalyst 3D menu there is a slider for Performance - Balanced - Quality. Should I leave it at Performance for my regular computing tasks and then push it to Quality if I want to play games? I don't even want to venture into the more advanced options. I'm confused

Also, the information section of the Catalyst lists this for my card:

Core Clock in MHz: 378 MHz
Memory Clock in MHz: 338 MHz

THe Newegg product info lists this:

Chipset/Core Speed: ATI RADEON 9800PRO/380MHz
Memory/Effective Speed: 128MB DDR/680MHz

Why is my memory speed only 338? Shouldn't it be in the 680 range?

Any help would be appreciated!

It's 680 DDR which is 340 base.

Why don't you just run the drivers at defaults and don't mess with them at all? If it ain't broke, don't fix it!

Yes, the card seems to be working VERY well at the default settings. Looks like I'll happily leave them there.
