I'm looking to upgrade my graphics card nothing crazy it will run the game I wanna play (mx simulator) but lags on the more detailed tracks. It's a 300w PSU. I've found that the hd7750 will work, but I'd rather find a cheaper video card. Having problems since the PSU is so low and id rather not upgrade it since the only reason I'm using this is for that game. Picked it up for 50 bucks today.
