[6] His first goal for the club came on 24 October in a League Cup third round tie against Hull City at Vicarage Road, exploiting a Ryan France error to net the second in a 2–1 win for Watford's first normal-time victory of the season.

[10] Priskin's first official Premier League goal came on 9 April 2007 in a 4–2 win against Portsmouth at Vicarage Road, netting the third of the game in the 50th minute from Steve Kabba's cross.

[11] He scored a second twelve days later against Manchester City on 21 April, equalising in the 75th minute from Douglas Rinaldi's pass for a 1–1 home draw, which nonetheless saw his team relegated.

[12] With Watford back in the Championship in 2007–08 following relegation, Priskin only made sparse appearances, being kept out of the side by Marlon King, Henderson and new signing Nathan Ellington.

On 8 March 2008, having not played a league game for three months, Priskin signed on a month-long loan at fellow Championship team Preston North End,[13] making his debut as a starter on the same day in a 2–1 win away at Charlton Athletic.

[16] He returned to Watford at the end of the loan, playing more regularly than before and featuring as a substitute in both legs of their 1–6 aggregate defeat to Hull in the play-off semi-finals.

[21] His improved performances came from November onwards under new manager Brendan Rodgers – during this time he scored most of his goals, established himself in the side, and became well known for his skill, pace, and deadly finishing.

[23] His first competitive goal for Ipswich came when he scored in a 2–1 League Cup second round 2–1 defeat at Peterborough United nineteen days after signing, later having a penalty saved by Joe Lewis.

In March 2015, the owner and main sponsor of the Győr filed for bankruptcy, which relegated the club to the third tier of the Hungarian football league system.

[36] On 16 June 2020, he became champion with Ferencváros by beating Budapest Honvéd FC at the Hidegkuti Nándor Stadion on the 30th match day of the 2019–20 Nemzeti Bajnokság I season.

He officially made his international debut for Hungary three days later, replacing Péter Halmosi for the final 21 minutes of a 1–2 friendly defeat against Argentina at the Ferenc Puskás Stadium in Budapest.

His greatest success with the national team came in late 2006 and early 2007, when he managed to score in five consecutive international games, a performance unseen in Hungary since the days of legendary players like Puskás or Ferenc Bene.

Due to his good performances for Watford towards the end of the 2008–09 he earned a recall to the Hungary squad for the FIFA World Cup qualifiers against Albania and Malta.
