I'm looking for a GPU that is compatible with a F1A55-M LX PLUS motherboard that is mid-priced but deliver amazing gaming quality. I've researched about six possible GPU but none of them fit what I want.
Somewhere around $100 or less. I don't want to buy an expensive one, but I'm only going up to $150. I'm not sure yet.
Have a look at the HD 7770: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127687 You may want to research about its power requirements and check if your current power supply can satisfy.
Will it support 1920x1080? Sorry for not mentioning this earlier but I don't see anywhere it could support 1080p.
Most modern cards support 1080p, and it has an HDMI port, so it must support 1080p. Check AMD's site if you wish to confirm.
