MSI kicked off its entry-level GeForce GT 720 lineup with as many as four models, two each of 1 GB and 2 GB, being fan-cooled, and passive-cooled. All four stick to NVIDIA reference clock speeds of 797 MHz core, and 1600 MHz DDR memory. Based on NVIDIA's entry-level
GK208 silicon (
Kepler architecture), the GT 720 features 192 CUDA cores, and a 64-bit wide DDR3 memory interface. All four cards launched by MSI are half-height and single-slot. All four feature
dual-link DVI, HDMI, and D-Sub display outputs.

If you want something with more GPU horsepower in the $50-75 range, it's better to go used. Or I have a BNIB MSI GTX750 1GB that I can sell you for a good price. However, if you just need a basic card for 2D, then the card I linked is more than enough.
