The Intel ARC B580 is supposed to be the Best Budget GPU but we found some serious problems when testing it as a GPU upgrade for older systems. This GPU isn't what you might expect if you wanted to replace a GTX 1660...in a lot of ways the B580 framerates and performance will be way below expectations.
