Does anyone know when the Houston microcenter restocks 30 series GPU's?

Hello @PC_Builder123 and thanks for posting on the Microcenter Community Forum. The store get random inventory trucks during the week. The best way to have a chance to get a 3000 series card from MC is to show up at the store 1-2 hours before it opens. Once you get into the store they'll let you know if they have any cards or if they are expecting a truck that day. They may give you a voucher and call you when the truck comes in. Or you may have to hang out in the store until it comes.

The 3000 series cards are limited, so only in store customers at the time they are re-stocked have first sell on these cards or any GPUs.

Choose a day this week, take a day off from work and visit the store Tuesday through Saturday.

Good Luck
