After two weeks start to learn OpenCL, I want to buy an ATI Radeon HD card. Based on my budget and my current PC (AMD Athlon 64 X2 Dual Core Processor, 250 watt power supply), I looked at the information provided on AMD website about card supported OpenCL.
I want to choose among these three: HD 5450, HD 5570, and HD 5670. Anybody can share their experience of using these cards ? Actually, I prefer HD 5570 (because of its low power)
