Do you guys know any low-end budget graphics card that doesnt require a strong psu. I don't want anything that is super extream but something that will run games like starcraft 2 maybe on high without any lag and its pretty cheap. I have a 400Watt psu. Its one of those lame psu that came with the case. Its a peace a trash but I want to go in with the graphics card before upgrading my psu
