Ireland silenced their critics with an impressive 46-24 victory over Argentina at the Aviva Stadium in Dublin on Saturday.
Ireland led from start to finish in a dominant display, outscoring their visitors seven tries to two.
Few would have expected such a one-sided clash after Argentina's recent win over Wales but the home side produced their best performance since pushing the All Blacks close in June to run the Pumas ragged.
The result ends Ireland's five-Test losing streak and secures their place among the second seeds for the 2015 World Cup draw.
Ireland raced to 24-9 lead by half time thanks to tries from debutant Craig Gilroy, fly-half Jonathan Sexton, hooker Richardt Strauss and full-back Simon Zebo. Argentina's only reply came via three penalties from pivot Nicolas Sanchez.
Unlike a fortnight ago when the Springboks turned the tables on Declan Kidney's men, the second half saw Ireland secure victory with two tries from Tommy Bowe and another from Sexton as the green-clad pack ruled in the tight exchanges and the backs hit their straps.
Argentina scored two consolation tries — via Tomas Leonardi and Juan Martin Fernandez Lobbe — in the final ten minutes but will be disappointed with their effort.
Gilroy got his international debut off to a perfect start by scoring a fabulous try after taking a flat pass from Sexton and beating handful of defenders, putting the hosts in front early on — and they never looked back.
Sexton grabbed his first try shortly afterwards with an equally good run to step his way to the whitewash. Strauss emerged from a line-out drive to crash over and give Ireland a 19-6 lead at the end of the first quarter. The result looked done and dusted.
Bowe and Sexton combined to send Zebo over the corner before the half-time whistle, handing the Ireland a 15-point headstart as the sides swapped ends.
Sanchez landed his fourth penalty of the afternoon to get the second half started but two tries in the space of four minutes from Bowe and Sexton ended any hopes of a comeback from the Pumas.
Bowe collected Sexton's chip ahead to gather and touch down before bagging his second after some fancy footwork from Gilroy and a final pass from Donnacha Ryan.
Argentina pushed hard for a try but to their credit, the Irish defence never backed off had held firm against multiple waves of heavy Argentine ball carriers.
The final Irish try arrived when Bowe pounced on Keith Earls' chip kick, but substitute Leonardi and skipper Fernandez Lobbe scored late tries from short range to give Argentina some respectability on the scoreboard.
Man of the match: A few candidates here and Jonathan Sexton deserves a mention for his two tries and getting the Irish backline going. But Ireland really won the game up front and Donnacha Ryan stood out, not only in the line-outs but for his tireless work cleaning out at the breakdown.
Moment of the match: The writing was on the wall early for the Pumas. Craig Gilroy's try was a great start to both the game and a promising Test career.
Villain of the match: Maximiliano Bustos was for a silly swing of a handbag — throwing the ball into the face of opposite number Cian Healy — so not worthy of the villain award.

Unlike their convincing successes over Australia and Argentina this month, victory didn't come easily for the French, who were trailing the Islanders going into the final quarter.
Predictions the All Blacks' attack would incinerate Wales' defence came to fruition in the first half especially. However even though the scoreline may read otherwise, it was a much better effort from the Welsh - the second half especially.
Scotland led 6-3 at half-time but second-period tries from Tukulua Lokotui and Fetu Vainikolo saw the Pacific Islanders earn their first ever Test triumph on the European stage
A superb second half fightback almost saw the home side pulling off a draw but a penalty from their fly-half Luciano Orquera, in the 79th minute, sailed just wide of the posts.
In a lacklustre but testy match, the Maori scored two tries to one plus 22 points from Willie Ripia.
Winger Fetu'u Vainakolo grabbed the opening score for the Islanders with a try after ten minutes, before the USA's Luke Hume looked to have levelled the scores only for this try to be ruled out for a forward pass.
A dominant first-half performance saw the visitors take a 14-3 lead into the interval thanks to Strauss's first try — off a rolling maul that Scotland failed to deal with — and three penalties from Pat Lambie.
With England, Wales, Scotland and Italy losing to southern opposition this weekend — Ireland were playing in a non-cap international — the French confirmed their status as the top European team in the world rankings.
The result is Canada's third consecutive win over the Bears.
Gilroy was the star of the show while Fergus McFadden grabbed two tries and Sean Cronin, Darren Cave and Luke Marshall added the gloss.
In front of a packed crowd at Twickenham, England opened the scoring with a penalty from Toby Flood with two minutes gone, but it was Australia who held the edge early on in terms of territory and possession.
The world champions led from start to finish to maintain their perfect record against Italy, who put up a solid challenge in the first half but ultimately couldn't match the visitors' attacking firepower.
Samoa sent Six Nations holders Wales crashing to their fifth consecutive loss after the visitors secured a 26-19 win at the Millennium Stadium on Friday.
In spells it was a performance that showed once again why the All Blacks are considered the finest exponents of attacking rugby in the game. It also backed up the importance of all players - from 1 to 15 - being comfortable in any position as forward duo Luke Romano and Wyatt Crockett proved.
Both sides conceded penalty tries in a three-minute span, Romania deliberately collapsing a maul, and Japan collapsing a scrum, to leave Japan leading by one with eight minutes to go.
The result brings an end to Australia's five-game winning streak against les Bleus and puts France in pole position in the chase for the all-important fourth place in the world rankings ahead of the World Cup pool draw next month.
In a tale of two halves, Ireland looked on course for a famous win after leading their visitors 12-3 at half-time.
Following an early blip whereby the islanders held the upper hand, England clicked into gear to claim a seven-try win that will please Stuart Lancaster.
When Wales had possession they were guilty of forcing passes, and their high error-count merely played into Argentina's hands. The only positive note for a disjointed home team was that they were in front approaching the last quarter of the match.
Italy warmed up for the visit of two heavyweights in the coming weeks with an unconvincing win over a feisty Tongan side.
The Americans ran in six tries to build a commanding lead by the hour mark but let their intensity drop in the final quarter to allow the Russians to bring a semblance of respectability to the scoreline.
The Pacific Islanders dominated from the start, scoring five tries — including four for debutant wing Robert Lilomaiava — to cruise into a 42-0 lead.
