I'm wondering GDDR3?

I have PCV-RS430G



I'm wondering if GDDR3 will work on my AGP 8x 3.0 interface



if it does is it good idea to get



HIS Hightech H165XTQT512GDDAN-R Radeon X1650XT 512MB 128-bit GDDR3 AGP 4X/8X IceQ Turbo HDCP Video Card



or



HIS Hightech H195PRQT512DDAN-R-V2 Radeon X1950PRO 512MB 256-bit GDDR3 AGP 8X IceQ 3 Turbo HDCP Video Card|||Do not confuse system RAM on the motherboard with videoram (Gddrx) on the graphics card. They are different and they have different jobs to do.

YES, a videocard with ddr3 will work GREAT on your 8XAGP. But take note that 512Mb is not always fully utilized in games.

The X1650XT AGP would draw about 60watts and the X1950 Pro AGP about 70watts. You might need a bigger power supply. Get one with dual +12V rails. Do not rely on minimum power supply recommendation. It will just run HOT at or near FULL LOAD. A bigger power supply would run cooler and last longer.
