The main qualifier here is a PCIe slot. No need to upgrade you power supply at all. Just plop down a new $140 Nvidia GTX 750 ti and away you go. Next gen console like experience for pennies on the dollar
These new cards have some AMAZING performance per watt. The 750 is something like 2-5 times more efficient than a lot of other GPU’s out there, and this model cna run PURELY on PCIE power. And this little guy runs Titanfall at better settings and performance than an Xbox one! That’s crazy performance for something being powered by a PCIe slot alone (no extra connectors to your PSU required).
So, if you’ve ever though about having unfettered access to decades worth of games, crazy cheap games overall, plus mods and all the other things that make PC gaming fun, and if you’ve got an old desktop lying around somewhere, you might wanna give this baby a look!
