Best Graphics Card Upgrade Options from a GTX 1060 3GB?

For around $150, check out the AMD 5600 XT priced around $120-130 or the 5700 XT, which might go for $150 used. Those would be your best bets without going over your budget.

With your budget, it's probably best to look for a used card. You might find a second-hand RTX 2070 for around that price. If you're open to alternatives, an Intel Arc A380 could work, or for more power, consider saving a bit longer for an A580.

If you're looking at the second-hand market, I'd suggest the RX 6600 which is around $220 new and almost twice as powerful as your current card. The RX 5700 XT is also a solid option; it might be cheaper used and performs similarly, but keep in mind it draws more power. If you can find one used, that could give you a great upgrade without breaking the bank.

Just saw a used Arc A750 listed for $175. If it's in good condition, that seems like a solid offer. It could be a great upgrade for your setup.

If you want something new, the options are limited at $150. The Arc A750 is priced at about $200, but it outperforms the RX 6600. You might find a used RX 6600 or the 6600 XT for $150-$200, so keep an eye out for deals.
