it doesnt matter if it's a DX9 card. for one, pete's OGL2 plugin doesnt need a DX9 card. you need the DX9 card for the shaders. unfortunately, the 5200 is too slow to use the shaders. turning off AA and AF, the ti4200 is much much faster than the 5200, even rivaling the 5600 i have (which is most certainly faster than a 5200)
