Argon E-114 vs. Ceepo Viper

Starting to look at Xmas presents for myself...lol, and these two are at the top of my list.
Anyone who has knowledge of these two rocket ships, your advice would be great.
Love the Ceepo Viper, but at $4200-$4700 for the frame set, its a bit high in price.
Saw a Argon (E-112) this weekend at TRI PTC and love the look. The rider said you really feel the difference coming off the bike after a long ride and helps the run transition (good when your in your mid 40's). I'm looking at the E-114 ($3400).
The old 2006 "Tri" tricked out Madone 5.2 has taking me as far as it can. Time for an upgrade before im to old to enjoy it.
You only live once and you cant take it ($$$) with you!!
