TJ, what's up buddy? Long time no see. I see you are still benching and taking names, lol. Nice X79 build you have there.
GPUs are something I'd love to see in the program, but it's highly unlikely that flagship cards would ever be submitted. It's not so much the cost of them, but instead it's the volume of chips being produced. Typically the flagship cards are using chips with a low yield rate. However, with Vendors like ASUS and Gigabyte manufacturing GPUs, it's possible that we could see them submitting some lower-end to mid-range GPUs. After all, they are participating in the program.
CPUs will just never happen. CPU review samples are hard to come by and they are only submitted to the most trustworthy hardware reviewers that would never violate the NDA. This will be left up to the gurus that work at Anandtech and such.
FYI: One of the best things about being in Newegg's program is that we are sometimes offered pre-launch products to review. I have already received a few of these assignments.
