Quick Answers

So, is GeForce RTX 4070 better than Mobility Radeon HD 5870 Crossfire?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 3,311 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while Mobility Radeon HD 5870 Crossfire is a 2010 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

GeForce RTX 4070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2010, 713.0% more raw performance headroom, more VRAM at 12 GB instead of 2 GB, and better frame-generation support with DLSS 3.5 + Frame Generation (2023) instead of FSR upscaling. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

Which one is the smarter buy today, not just the cheaper card?

GeForce RTX 4070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 4070 is about $201 cheaper on MSRP at $599 MSRP versus $800 MSRP, and you are getting 713.0% higher G3D Mark. It also leads G3D-per-dollar by 985.8%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Mobility Radeon HD 5870 Crossfire still worth buying for gaming in 2026?

Yes. Mobility Radeon HD 5870 Crossfire is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around $800 MSRP, even if GeForce RTX 4070 is still the cleaner recommendation on overall value today.
