The 970 is still a fantastic card for the price and should hold up for a a few years at the least. Most people wouldn't have even realized or noticed the memory issue. Not saying what they did is right, but it's a non-issue for me.
Otherwise, some other notes on my build:
I was going to get at least a 2TB hard drive, but Best Buy had a faster 1TB on sale for $39, and that was too good to pass up. I'd rather have a faster drive than settle for a slower one with a bit more capacity.
I also found a 256GB SSD on sale for about $90 which was also a great price, and makes my above point even more.
Switched from a small water cooler to a fan cooler. Not overclocking and don't intend to. Could have gotten away with stock cooler, but a $30 investment is a good fan cooler is a smart move I think.
Some of these changes allowed me to save a nice bit of money without giving up any performance.
