Quick Answers

So, is Xeon E3-1290 v2 better than Opteron 6276?
Yes. Xeon E3-1290 v2 is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 0.1% 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 E3-1290 v2 is the better pick. According to our tests, it delivers 0.1% 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 E3-1290 v2 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E3-1290 v2 is still the faster CPU overall, but Opteron 6276 is easier to justify if budget matters more than peak performance. Xeon E3-1290 v2 comes in 12.3% more expensive on MSRP at $885 MSRP versus $788 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Opteron 6276 is also 12.2% better value on MSRP (8.1 vs 7.2 PassMark/$), 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 E3-1290 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 16/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
