you'll not be able to buy hardware that runs gnome 3.6 on rhel7 after even a few years....
RHEL gets tons of backports for cpu and chipset support, but for graphics it tends to be much more time limited.

This might have been true for RHEL5, RHEL6 GPU support is quite different and involves fully supporting new HW for most of the lifetime of the product.
RHEL7 will continue in the RHEL6 model I would guess.
