they are both XFX cards, and AFAIK they allow overclocking. for $20 he could get the OC'd version and push it further, since the OC'd card are cherry picked to run at higher clocks.
XFX also boasts a true lifetime warranty, and taking it one step further, you can transfer the backing to a second owner. For frequent upgraders that sell off their used equipment, XFX's Double Lifetime Warranty, as it's dubbed, makes for a great marketing bullet on EBay or trading forums. And in a move to remain competitive on paper, as of April 17th, XFX now also allows end users to overclock the card and replace the heatsink/fan assembly. Unfortunately, they've also adopted the same vexatious 30-day registration policy and accompanying penalty for non-compliance as EVGA.
