GPU for Simplified Fuzzy ART MAP

hello! I have a task to develop a neuronal network for data processing. Which GPU card should I choose?


network type: Simplified Fuzzy ART MAP
min refresh rate in executing mode (non training): 1-2 per second
input size: 300 X 300 (if i right understand structure this net)
initial number of classes: 20
IMPORTANT! The number of networks that need to work together: 5-7

Money is not a problem, but I want chose optimal system and understand the reasons! Thanks!
