Quick Answers

So, is Xeon E3-1240 v3 better than Xeon W3680?

It depends on what you want from the system. For gaming, Xeon E3-1240 v3 is ahead with a 1.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon W3680 pulls ahead with 0.3% better PassMark. Xeon W3680 also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon W3680 is the stronger fit. You are getting 0.3% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Xeon E3-1240 v3 is still the faster CPU overall, but Xeon W3680 is easier to justify if budget matters more than peak performance. Xeon E3-1240 v3 comes in at an unclear MSRP at unclear MSRP versus $594 MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon W3680 is still stronger for heavier multi-core work with 0.3% better PassMark. Xeon W3680 is also 100.0% better value on MSRP (11.8 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Xeon E3-1240 v3 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010). That makes it the safer long-term bet.
