Sup guys. As the title suggests, I'm looking for the best GTX 680 that is under $500 and works with 550W power supply. I've been thinking of getting the Gigabyte WindForce 2GB ( http://www.newegg.com/Product/Product.aspx?Item=N82E16814125442 ) since the benchmarks here seem to take it in great favor. I'm not going to SLI or overclock right now, but in the future I might. What do you guys think?
