Which video card will allow me to run SC II?

[SRuNz]

I'm on a very low budget for a video card which brings me to the question, which video card will allow me to run and play sc 2? As long as it allows me to play it; even if it I have to play with the lowest settings.

I was considering buying an ASUS GeForce 8400 GS EN8400GS 512MB DDR2. Will this run sc 2? or will I need to invest in something like the GeForce GT 240 with 1 GB GDDR5?

I have that EXACT 8400GS, but i can only run SC2 beta on low/medium settings or I will get lots of lag... you should get at least a 9800GT or GTS 250.
