Quick Answers

So, is Xeon E3-1270 v2 better than Xeon X5675?

Yes. Xeon E3-1270 v2 is the better all-around CPU here. It gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data, 1.2% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E3-1270 v2 is the better pick. According to our tests, it delivers 0.5% 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, Xeon E3-1270 v2 is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E3-1270 v2 is still the faster CPU overall, but Xeon X5675 is easier to justify if budget matters more than peak performance. Xeon E3-1270 v2 comes in at an unclear MSRP at unclear MSRP versus $1,440 MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data. Xeon X5675 is also 100.0% better value on MSRP (4.5 vs 0.0 PassMark/$), 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 E3-1270 v2 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011) and more multi-core headroom with 4 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
