Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Very weak future-proofing: 2010-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
383.8% HIGHER MSRP
$479 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 2.5 vs 11.8 G3D/$ ($479 MSRP vs $99 MSRP).
❌57.9% longer card at 229mm vs 145mm.

GeForce GT 640

2012

Why buy it

✅Costs $380 less on MSRP ($99 MSRP vs $479 MSRP).
✅Delivers 377.7% more G3D Mark for each dollar spent, at 11.8 vs 2.5 G3D/$ ($99 MSRP vs $479 MSRP).
✅Measures 145mm instead of 229mm, a 84mm shorter card that is more SFF-friendly.

Quick Answers

So, is FirePro V5800 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 1,184 vs 1,169 in G3D Mark. The bigger reason to prefer FirePro V5800 is the overall package: you are getting no meaningful modern upscaling stack.

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

FirePro V5800 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?

FirePro V5800 is the smarter buy by a wide margin. FirePro V5800 is about 383.8% more expensive on MSRP at $479 MSRP versus $99 MSRP, and you are getting 1.3% 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 FirePro V5800?

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 newer architecture and staying closer to $99 MSRP more than squeezing out the extra headroom of FirePro V5800. The trade-off is that FirePro V5800 currently gives you 1.3% higher G3D Mark. GeForce GT 640 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
