Is the XFX Speedster MERC310 RX 7900 XTX right for you?
If you find this MERC310 at a clear discount and want strong 4K rasterisation with 24GB VRAM, a high boost clock, and premium triple-fan cooling, and heavy RT isn't a priority, it's excellent value.
If you want strong ray tracing in heavy path-traced titles or the latest FSR 4 upscaling, the 7900 XTX trails. A current RDNA 4 card or an RTX equivalent makes more sense for those priorities.
Before you buy
Yes at a clear discount for raster-focused 4K gaming. The 24GB VRAM and strong rasterisation hold up well. The main caveat is weaker ray tracing than Nvidia and no FSR 4 support.
Yes. The MERC triple-fan cooling solution keeps the 355W TDP in check with quiet sustained operation, and the high factory boost clock gives a small performance edge over reference cards.
No. The 7900 XTX is RDNA 3, which supports FSR 3 but not the newer RDNA 4-exclusive FSR 4. FSR 3 is good but trails current FSR 4 and DLSS 4 image quality in supported titles.
XFX recommends 800W for the 7900 XTX. With a power-hungry CPU, a quality 850W unit gives more headroom against the 355W TDP and transient spikes.
