To Use AVGA Card or Normal GFX card with Powerstrip on Scart TV??

[lettuce]

I am 2 minds weather to use a AVGA card or normal PC card using powerstrip with my new cab? I have a Toshiba 28" TV, which i have used on a AVGA card already, but the picture has some overscan problems, and i cannot find a service menu code for this model TV to help sort this problem, although the only game i tried this on was Final Fight, but im guessing each game with different resoultions would have different sizes of overscan?, or would the overscan be the same for every game no matter what the resoultion???.

Anyway i want my games looking as authentic as possible and cant fault the clarity and quality of picture on the TV, now i know Powerstrip has a overscan option, but am told that powerstrip doesnt like the AVGA card, so if i wanted to use powerstrip id have to use a normal PC card. Can you get a Normal PC GFX card to act just time a AVGA card, and is it worth the hassel of setting up powerstrip to use all the correct resolutions for mame? As i have heard side by side that a AVGA based cab will look better than a cab running powerstrip?

Is there a windows program about that can adjust overscan problems?
