Hi, recently I've been looking at the radeon 7770 cards for under 130$ on Amazon. I'm wondering which brand would be the best performance wise for gaming. I'm currently looking at http://www.amazon.com/ASUS-HD7770-DC-1GD5-V2-Radeon-GDDR5-Graphics/dp/B007RFYFH0/ref=sr_1_20?s=pc&ie=UTF8&qid=1343284738&sr=1-20&keywords=radeon+7770 and http://www.amazon.com/Sapphire-11201-02-20G-Radeon-PCI-Express-Graphics/dp/B00782U10C/ref=sr_1_23?s=pc&ie=UTF8&qid=1343284900&sr=1-23&keywords=radeon+7770. I was wondering about the dvi and mini dp though. What would be the differences?
