I'm at work right now- don't remember all my system specs off hand, but
Desktop
8 GB system RAM
AMD - Radeon something card with 1GB RAM (no fan)
Just looking for a good video card, not going to buy a new PC.
I'd like to spend less than $200
Pretty much anything in the $150 to $200 range will work just fine.
AMD R9 270 is a great bang for buck card.
Nvidia 750 ti runs great on low wattage systems.
AMD 7850 is an older model but at a great price. Still performs.
Make sure to verify your power supply has enough power and connectors first.
