Quick Answers

So, is Core i7-3770K better than Xeon E7340?

Not really, because they are built for different jobs. Xeon E7340 makes more sense for workstation-style multi-core throughput, while Core i7-3770K is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Xeon E7340 is the stronger fit. You are getting 0.8% better PassMark.

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

Core i7-3770K is still the faster CPU overall, but Xeon E7340 is easier to justify if budget matters more than peak performance. Core i7-3770K comes in 55.9% more expensive on MSRP at $332 MSRP versus $213 MSRP, and it still gives you a 9.7% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E7340 is still stronger for heavier multi-core work with 0.8% better PassMark. Xeon E7340 is also 57.0% better value on MSRP (30.7 vs 19.6 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i7-3770K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2007). That makes it the safer long-term bet.
