Just got a gigabyte 7970 and not positive my psu is good enough. Its 500 watt evga w1 which is about the cheapest one i could find at the time. I have a g3258 oced to 4.0ghz at 1.25v(very disappointed there) soon to be 2 250gb samsung evo ssd's, 3x 4gb sticks of ram, i know everyone says a quality 500w will work just not sure about my cheapo. I will be getting an evga g2 650 soon but im dangerously low on disc space so i want to get that 2nd ssd with my next check. What would you guys do if you were in my position. And one more thing, down the road ill be getting an i7 4790k and 980 ti, the 650w evga g2 would be a solid choice for that right? Thanks on advance
