My HP p7 1157c has a 300w PSU and a A6 3600 CPU at 2.1Ghz (which I don't know too much about) and about 8 gigs of RAM. I'm looking for a GPU that would run CS:GO (competitive) on a 22' widescreen monitor at 1920 x 1080 native res. I was looking/researching the Radeon HD 7750 as well as the 7770 since they use very little power. Was wondering which card would I be better off purchasing?
So should I go for the 7750? Or perhaps just purchase a more powerful PSU and then the 7770 to go with it? Wouldn't that just bottleneck my cpu and cause problems? I know my PC blows either way but I'm trying to make the best with what I have here.
