The 6700XT and 6750XT are probably the best deals recently for graphics cards. Look for either of them for under $350, I have even seen 6750XT cards for close to $300. Both have 12GB of memory, which is a great amount for that price point. I believe the hardware is the same basically, the 6750XT is just higher clocked, such that it often goes head to head with an RX 6800, which is often closer to a $500 card.
