GA-7S748 video card needed

I currently have a GigaByte 7S748 Mobo with an older MadDog 128mb video card that keeps over heating due to a faulty fan on it and I would like to have something a little better to play some games. Its running 2700+ with pc3200 2Gb ram. I shop newegg and would like to keep it under $100. It needs a AGP 4x/8x card I think ?
Does anyone know if either of these would work :BFG Tech BFGR62256OC GeForce 6200 256MB 64-bit DDR AGP 4X/8X Video Card - or 3D Fuzion 3DFR66256 GeForce 6600 256MB 128-bit DDR AGP 4X/8X Video Card ? They both ask for a An available AGP 2.0 slot and I am not sure if the GA-7S748 has a 2.0 or a 1.0 slot ?
They both ask for A minimum 300W system power supply and I have a 450 power supply

Hey discboy,

I would like to first say that spending anywhere near $100 on an AGP card would be a poor investment. This new card will help your computer--but even with the upgrade it will be completely obsolete in a year at the most.

Since your PSU is quite adequate your best GPU options are:

Best gaming value and my recommendation:
ATI 4650--$69

ATI 4670-$97 (most powerful agp card on market)

OR-- look on ebay/craigslist for a used card. The used market is flooded with older performance-class AGP cards that enthusiasts no longer want. I wouldnt take this kind of risk for a large purchase--but I bet you can find a very decent Nvidia 7 or 8 series card for like $25-50 (best option--just make sure you see it working before you pay)
