I just got a desktop from a computer store that furbishes engineering computers for personal use. Right now I'm using the basic graphics chip built into the motherboard, but I would like to get a new graphics card for gaming. I have a PCI express slot and a 350 watt power supply charger. The kind of games I'd like to play are a few years old (Elder Scrolls IV era). What graphics cards would you suggest I look into buying with a $150 budget? Let me know if you need more info.
