Help choosing GPU

I'm doing my first build in May and I can't decide which GPU to get. Here are the specs:

Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard
Power Supply: Corsair CX 600W 80 PLUS Bronze Certified ATX12V Power Supply
CPU: Intel Core i7-3770K 3.5GHz Quad-Core Processor
RAM: Crucial Ballistix Sport 16GB DDR3-1600 PC3-12800)
Hard Drive: HGST Deskstar 7K1000.C 1TB 7,200 RPM SATA 3.0Gb/s
Case: Diablotek EVO Mid Tower ATX Computer Case
Disc Drive: Lite-ON 24X SATA DVD Burner - OEM
CPU Cooler: Thermaltake Silent Intel LGA1156 CPU Cooler with 4-Pin PWM Function

I'm trying to keep it under $100. Here are 2 options I've found:

Thanks in advance!

P.S.: I won't be doing extreme gaming; I want to record and play Minecraft and do some video editing and some Photoshopping.
