Quick Answers

So, is V-Series V120 better than Xeon E5345?

Not really, because they are built for different jobs. Xeon E5345 makes more sense for workstation-style multi-core throughput, while V-Series V120 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, V-Series V120 is the better pick. According to our tests, it delivers 1.0% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, V-Series V120 is the stronger fit. You are getting 0.3% better PassMark, backed by 1 cores and 1 threads.

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

V-Series V120 still makes the most sense overall. V-Series V120 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data.

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

V-Series V120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2006) and more multi-core headroom with 1 cores / 1 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
