I'm trying to get ideas for the best possible upgrade for my 5770. My computer is 3 and a half years old and I'm hoping it will get me well into the next generation with a new video card. I game at 1080p, so I don't need anything that supports crazy resolutions. Just equal to or better than PS4/Xbone. I'm looking at a budget of $200, unless I can convince my wife otherwise.
AMD Phenom II X4 955 3.2 ghz
4 gb ram
700W power supply
Windows 7 64 bit
I was also wondering if getting another 4 gb of ram will be necessary. I don't do a lot of multi-tasking other than alt+tabbing to Chrome for a walkthrough or something. I keep as few processes running at once as possible. Mostly just Steam and basic PC stuff.
