Quick Answers

So, is Core i7-975 better than Phenom II X6 1075T?

Yes. Core i7-975 is the better overall CPU here. You are getting 0.8% better PassMark, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, Core i7-975 is the better fit because it leads the single-thread side of the matchup with 2.9% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Core i7-975 is the better fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads. It also carries the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Core i7-975 is the smarter buy by a wide margin for a fresh build. Core i7-975 is 307.8% more expensive on MSRP at $999 MSRP versus $245 MSRP, and it gives you 0.8% higher PassMark. Phenom II X6 1075T only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2010 platform. Even with 304.6% better value on paper (14.3 vs 3.5 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Phenom II X6 1075T is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term pick.
