Get a better PSU too. The GTX 960 will be a good upgrade.
Yeah, I'm think so. But the question is what brand of power supply do I chose. Most people said Seasonic s12II 620 watt is good one. In my country is on sale for only 40 US dollars. But the Corsair they not recommended VS version but the CX version is too expensive for me. Gigabyte gtx 960 2Gb/4Gb would be the most perfect for me.
