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.
Here are the cheapest 6700XT and 6750XT cards on Newegg. Obviously there are other options as well, but I personally would pay the extra $30 for the 6750XT between these two. Don't forget the $20 promo code on the 6750XT, and both come with a free game, RE4.
