I'm building a PC right now and I'm trying to decide on which GPU to get. I'm on a very tight budget so I cant spend much but want to get the best for my money. I'm deciding between this http://www.amazon.com/EVGA-Superclock-Dual-Link-Graphics-02G-P4-3753-KR/dp/B00IDG3IDO/ref=sr_1_6?s=electronics&ie=UTF8&qid=1397689403&sr=1-6&keywords=gtx+660 and this http://www.amazon.com/Gigabyte-PCI-Express-Displayport-Graphics-GV-N660OC-2GD/dp/B00942TK8I/ref=sr_1_2?s=electronics&ie=UTF8&qid=1397689403&sr=1-2&keywords=gtx+660. I checked my specs and my build can support both I just want some more info on which I should get. Thanks.
