Quick Answers

So, is GeForce GTX 680M KY_Bullet Edition better than Maxwell GPU Surface Book (940M, GDDR5)?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 3,569 vs 3,500 in G3D Mark. The bigger reason to prefer GeForce GTX 680M KY_Bullet Edition is the overall package: you are getting no meaningful modern upscaling stack.

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

GeForce GTX 680M KY_Bullet Edition is the safer long-term GPU choice because it gives you the stronger overall hardware and feature outlook for modern games.

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

GeForce GTX 680M KY_Bullet Edition is the smarter buy by a wide margin. GeForce GTX 680M KY_Bullet Edition is priced in an unclear MSRP range at an unclear MSRP versus $150 MSRP, and you are getting 2.0% higher G3D Mark. Maxwell GPU Surface Book (940M, GDDR5) really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Maxwell GPU Surface Book (940M, GDDR5) make more sense than GeForce GTX 680M KY_Bullet Edition?

Yes. Maxwell GPU Surface Book (940M, GDDR5) is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, lower power draw (30W vs 122W), and staying closer to $150 MSRP more than squeezing out the extra headroom of GeForce GTX 680M KY_Bullet Edition. The trade-off is that GeForce GTX 680M KY_Bullet Edition currently gives you 2.0% higher G3D Mark. Maxwell GPU Surface Book (940M, GDDR5) still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
