Can I use a Core i7 in the GIGABYTE MW53-HP0?

No. It takes LGA 4677 Xeon W-2400/2500 or W-3400/3500 processors. Consumer Core chips do not fit.

Will an 8th gen Core i5 work in the ASRock Z270 Killer SLI/ac?

No. Z270 supports 6th and 7th gen LGA 1151 chips. The 8th gen needs a 300-series board despite the same socket.

Which is better for a workstation?

The GIGABYTE. It offers 8 DDR5 RDIMM slots, four PCIe Gen5 x16 slots and Xeon W support up to 385W. The ASRock is a consumer board from 2017.

Is the GIGABYTE worth $747.10?

Only if you need Xeon W and PCIe Gen5. That price at Walmart as of November 7, 2026 buys the board alone, before a CPU or RDIMM memory.

The GIGABYTE, on paper. It is a current platform with newer components. The ASRock's Z270 platform has been out of production for years, so replacement parts are used-only.

Do both fit a standard ATX case?

Yes. Both are ATX boards. The GIGABYTE measures 304.8 x 244 mm, so check clearance around the top and front edges.
