Curious, whats stopping me from getting these deals now, returning the 7700x cpu later, and keeping the ram for myself?
You can't just return the processor, you have to return the bundled processor and ram. For the motherboard bundles, if you just return the motherboard, you get back the price of the motherboard with the $20 taken off of it.
No clue how much better it is, but Corsair has CL30 DDR5-6000 for right around $200. Major difference? Highly unlikely, but my new build has a pile of Corsair stuff in there, so I wanted it for aesthetics, too. Honestly, I don't think they'll keep those deals around for the 3D processors unless they end up being disappointing. Those bundles are trying to move stuff that otherwise wouldn't. If they end up being disappointing, I might even look in the Intel direction.
Yeah, if you're looking for Corsair RGB stuff to match the rest of the build, that makes sense. Still can't beat a $150 ddr5 kit though for free, especially when their CPU prices are still the lowest around. The 7950x combo will do for me, it's in a Lian Li with no windows so I don't even need to worry about cable management.
