Which is better for gaming?

The Gigabyte, if you pair it with a modern 8th or 9th gen CPU. The bundled 4790K in the ASUS is still playable but is a decade-old 4-core chip, and the Z97-A's SLI support does not help with today's single-GPU games.

The Gigabyte. It takes current DDR4 and 8th/9th gen CPUs, while the ASUS is stuck on DDR3 and LGA 1150 with no upgrade path.

Is the Gigabyte worth the extra over the ASUS bundle?

At $83.77 at eBay as of November 7, 2026, the Gigabyte board alone is cheaper than most working 4790K bundles, but you still need a CPU and DDR4. Add those and the ASUS bundle can win on total cost if you already have DDR3.

Can I use my old DDR3 in the Gigabyte board?

No. The B365M DS3H takes DDR4 only. DDR3 from an older build will not fit.

Does the ASUS bundle need a separate CPU cooler?

The 4790K runs hot, especially overclocked, so plan on an aftermarket cooler rather than the stock unit.

Which has more memory capacity?

The Gigabyte, at 64 GB across four DDR4 slots versus 32 GB of DDR3 on the ASUS.

ASUS Z97-A with i7-4790K vs Gigabyte B365M DS3H Motherboard

These are two different platforms, not two versions of the same board. The ASUS Z97-A bundle pairs a 2014 LGA 1150 board with an unlocked Core i7-4790K and DDR3, so it only makes sense if you already own DDR3 and want a cheap 4-core/8-thread setup. The Gigabyte B365M DS3H is a current-enough LGA 1151 board for 8th and 9th gen Intel chips with DDR4 and up to 64 GB, and at $83.77 at eBay as of November 7, 2026 it is the cheaper and more upgradable path. Buy the Gigabyte unless the bundled 4790K is the whole point.
