GeForce GT 640

2012

Why buy it

✅Costs $601 less on MSRP ($99 MSRP vs $700 MSRP).
✅Delivers 593.4% more G3D Mark for each dollar spent, at 11.8 vs 1.7 G3D/$ ($99 MSRP vs $700 MSRP).
✅Measures 145mm instead of 198mm, a 53mm shorter card that is more SFF-friendly.

Trade-offs

❌Very weak future-proofing: 2012-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

NVS 810

2015

Why buy it

✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Quick Answers

So, is NVS 810 better than GeForce GT 640?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,169 vs 1,192 in G3D Mark. The bigger reason to prefer NVS 810 is the overall package: you are getting a newer generation, no meaningful modern upscaling stack.

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

GeForce GT 640 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?

NVS 810 is the smarter buy by a wide margin. NVS 810 is about 607.1% more expensive on MSRP at $700 MSRP versus $99 MSRP, and you are getting 2.0% higher G3D Mark. GeForce GT 640 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does GeForce GT 640 make more sense than NVS 810?

Yes. GeForce GT 640 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 future-proofing and staying closer to $99 MSRP more than squeezing out the extra headroom of NVS 810. The trade-off is that NVS 810 currently gives you 2.0% higher G3D Mark. GeForce GT 640 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
