500$ for 1080, it should be the very good deal. What's the GPU brand and its model?
I could reach the best local distributor via my group buy, but the best price for 1080 is about 577$ which is much more expensive than your deal.
EVGA GeForce GTX 1080 FTW GAMING, 08G-P4-6288-RX, 8GB GDDR5X, HYBRID & RGB LED
Yeah I'm thinking for the price I cant beat it. Just offered him $1800. Waiting on reply
